1. Bohrium (pronounced /ˈbɔəriəm/) is a chemical element with the symbol Bh and atomic number 107 and is the heaviest member of group 7 (VIIB).
The first convincing synthesis was in 1981 by a German research team led by Peter Armbruster and Gottfried Münzenberg at the Gesellschaft für Schwerionenforschung (Institute for Heavy Ion Research) in Darmstadt using the Dubna reaction.
Bi+Cr-->Bh+n
In 1989, the GSI team successfully repeated the reaction during their efforts to measure an excitation function. During these experiments, 261Bh was also identified in the 2n evaporation channel and it was confirmed that 262Bh exists as two states - a ground state and an isomeric state.
The IUPAC/IUPAP Transfermium Working Group (TWG) report in 1992 officially recognised the GSI team as discoverers of element 107.

2.Hassium (pronounced /ˈhæsiəm/  HAS-ee-əm or /ˈhɑːsiəm/[1] HAH-see-əm) is a synthetic element with the symbol Hs and atomic number 108 and is the heaviest member of the group 8 (VIII) elements. The element was first observed in 1984.
Hassium was first synthesized in 1984 by a German research team led by Peter Armbruster and Gottfried Münzenberg at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt. The team bombarded a lead target with 58Fe nuclei to produce 3 atoms of 265Hs in the reaction:
Pb(Fe,n)Hs
The IUPAC/IUPAP Transfermium Working Group (TWG) recognised the GSI collaboration as official discoverers in their 1992 report.
The name hassium was proposed by the officially recognised German discoverers in 1992, derived from the Latin name for the German state of Hesse where the institute is located (L. hassia German Hessen).

3.Meitnerium (pronounced /maɪtˈnɛəriəm/ myet-NAIR-ee-əm or /maɪtˈnɜriəm/ myet-NER-ee-əm) is a chemical element with the symbol Mt and atomic number 109. It is placed as the heaviest member of group 9 (or VIII) in the periodic table but a sufficiently stable isotope is not known at this time which would allow chemical experiments to confirm its position, unlike its lighter neighbours.
Meitnerium was first synthesized on August 29, 1982 by a German research team led by Peter Armbruster and Gottfried Münzenberg at the Institute for Heavy Ion Research (Gesellschaft für Schwerionenforschung) in Darmstadt.[1] The team bombarded a target of bismuth-209 with accelerated nuclei of iron-58 and detected a single atom of the isotope meitnerium-266:
Bi(Fe,n)Mt

4.Darmstadtium (pronounced /dɑrmˈʃtætiəm/ ) darm-SHTAT-ee-əm, formerly known as ununnilium, is a chemical element with the symbol Ds and atomic number 110. It is placed as the heaviest member of group 10 but a sufficiently stable isotope is not known which would allow chemical experiments to confirm its place. This synthetic element is one of the so-called super-heavy atoms and was first synthesized in 1994.
Darmstadtium was first created on November 9, 1994 at the Gesellschaft für Schwerionenforschung (GSI) in Arheilgen, a northern suburb of Darmstadt, Germany by Peter Armbruster and Gottfried Münzenberg, under the direction of professor Sigurd Hofmann. Four atoms of it were detected by a nuclear fusion reaction caused by bombarding a lead-208 target with nickel-62 ions: [1]
Pb(Ni,n)Ds
In the same series of experiments, the same team also carried out the reaction using heavier nickel-64 ions. During two runs, 9 atoms of 271Ds were convincingly detected by correlation with known daughter decay properties: [2]

The IUPAC/IUPAP Joint Working Party (JWP) recognised the GSI team as discoverers in their 2001 report.

5.Roentgenium (pronounced /rɛntˈɡɛniəm/ or /rʌntˈɡɛniəm/ ) is a synthetic radioactive chemical element with the symbol Rg and atomic number 111. It is placed as the heaviest member of the group 11 (IB) elements, although a sufficiently stable isotope is not known at this time that would allow its position as a heavier homologue of gold to be confirmed.
Roentgenium was officially discovered by Peter Armbruster, Gottfried Münzenberg, and their team working at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany on December 8, 1994.[1] Only three atoms of it were observed (all 272Rg), by the cold fusion between nickel ions and a bismuth target in a linear accelerator:
Bi(Ni,n)Rg
In 2001, the IUPAC/IUPAP Joint Working Party (JWP) concluded that there was insufficient evidence for the discovery at that moment in time.[2] The GSI team repeated their experiment in 2000 and detected a further 3 atoms.[3][4] In their 2003 report, the JWP decided that the GSI team should be acknowledged as the discoverers.

6. Ununbium is a synthetic radioactive chemical element with the temporary symbol Uub and atomic number 112. "Ununbium" (pronounced /uːnˈuːnbiəm/ oon-OON-bee-əm) is a IUPAC systematic element name, used until the element receives an accepted name.
Ununbium was first created on February 9, 1996 at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany by Sigurd Hofmann, Victor Ninov et al.[6] This element was created by firing accelerated zinc-70 nuclei at a target made of lead-208 nuclei in a heavy ion accelerator. A single atom (the second has subsequently been dismissed) of ununbium was produced with a mass number of 277.[6]
208Pb+70Zn-->278Uub-->277Uub+1n
In May 2000, the GSI successfully repeated the experiment to synthesise a further atom of Uub-277.[7][8] This reaction was repeated at RIKEN using the GARIS set-up in 2004 to synthesise two further atoms and confirm the decay data reported by the GSI team.

From Wikipedia, the free encyclopedia

In physics, the atomic form factor, or atomic scattering factor, is a measure of the scattering amplitude of a wave by an isolated atom. The atomic form factor depends on the type of scattering, which in turn depends on the nature of the incident radiation, typically X-ray, electron or neutron. The common feature of all form factors is that they involve a Fourier transform of a spatial density distribution of the scattering object from real space to k-space (also known as reciprocal space).

例：在弹性电子散射实验中，电子的能量为400MeV，Form Factor的平方函数可以通过散射角表示，设核半径为2，4，6fm，则可绘制出如下的函数图：

第一到第三图是分别在三个坐标系内的函数图像，在第四图中能很清楚看出随着核半径的增大，虽然宏观上来看增幅很小，仅2fm。但是对应的函数却表现出了更加剧烈的减幅振荡。该图也符合均匀对称球体的Formfactor图像.

叉烧肉
材料：猪肉、李锦记叉烧酱、生粉（少许）、糖（少许）、油
做法：
1，把猪肉切成大约1.5－2CM 厚的许多片大片，然后用刀背在猪肉的两面细剁各一遍，把猪肉剁软，以便入味；
2，用生粉和糖各少许在每片猪肉的两面涂均匀，腌片刻；
3，然后用调羹舀出叉烧酱，厚厚地涂抹在猪肉片的两面，记住，要厚厚的。用量大约是1LB 的猪肉配5 汤匙左右的叉烧
酱，反正要达到把猪肉的底面都浆满叉烧酱的效果；
4，蒙上保鲜纸，放进冰箱里腌过夜（一般我们是下午调味，腌到第二天近中午才拿出来）；
5，烧热油锅，大火热锅时放下猪肉块用油煎，待肉与锅接触的那面转了颜色后立刻翻转煎另一面，看到转色了，就调回小
火，慢慢煎熟，注意火候，不可太频繁地翻也尽量不要煎焦了。煎至筷子可以戳穿猪肉块时，美味的简易叉烧就做好了！
心得：
1，挑选猪肉中叫“夹心肉”的部分，这部分的肉以瘦肉为主，中间略夹一些肥的脂肪层，肉质特别好味（但如有硬筋，要
剔去），而且烧的过程中脂肪层融了，令叉烧内略油脂，口感更香美；
2，千万不要按照李锦记叉烧酱瓶子上贴的说明书指示的份量及腌制时间去做叉烧，按他们指示的作出的叉烧味道不好，而
且淡；下的叉烧酱份量要足，腌的时间要够长！而且说明书上虽然说是烤，但是变烤为煎更健康，不容易上火，味道也一
样好！^_^
3，先大火热锅两面煎腌好的肉，可以令肉的表面在短时间内熟了薄薄的一层，封住里面没有熟的肉的肉汁，然后再转小火
慢煎，这样弄出来的叉烧里面很鲜，而且软，不会太干硬的。
4，用刀背拍松，利于入味；但糖和生粉绝不能多下.
