测量了三种中子最缺乏的锌同位素在铍靶上345 MeV/核子的弹丸破碎过程中产生的截面。虽然结果比在镍靶上用75 MeV/核子的光束得到的结果小一个数量级以上，但在高能破碎的情况下，发现反应产物的速率更大。在磨损-烧蚀模型的框架下，对锌和氪之间的大多数中子亏缺同位素的实验截面进行了分析。当使用Hartree-Fock-Bogoliubov质量模型的一种特殊变体所预测的核质量时，发现与数据非常吻合。从放射性的角度讨论了在该地区观测更多外来同位素的前景。
The cross sections for the production of three most neutron-deficient zinc isotopes,, in the projectile fragmentation ofat 345 MeV/nucleon on a beryllium target, were measured. Although the results are smaller by over an order of magnitude from those obtained with abeam at 75 MeV/nucleon on a nickel target, the rates of reaction products are found to be larger in the case of high-energy fragmentation of. The experimental cross sections for the most neutron-deficient isotopes of even-nuclei between zinc and krypton were analyzed in the framework of the abrasion-ablation model. A very good agreement with the data was found when the nuclear masses predicted by a particular variant of the Hartree-Fock-Bogoliubov mass model were used. The prospects for the observation of more exotic isotopes in this region are discussed in context ofradioactivity.
