摘要:

本文介绍了142 MeV/u ~(48)Ca束分裂产生丰中子核的测量结果。在净中子拾取过程中,发现了一种新同位素的产生证据,这种同位素是中子最丰富的硅核素44 Si。一个简单的系统框架被发现来描述生产截面的基础上从激发prefragments,允许外推到其他弱反应产物的热蒸发。

英文摘要:

The results of measurements of the production of neutron-rich nuclei by the fragmentation of a 48Ca beam at 142 MeV/u are presented. Evidence was found for the production of a new isotope that is the most neutron-rich silicon nuclide, 44Si, in a net neutron pick-up process. A simple systematic framework was found to describe the production cross sections based on thermal evaporation from excited prefragments that allows extrapolation to other weak reaction products.
