摘要

介绍了核乳化液中 1.2 A GeV $^7$Be 核外围碎片的电荷拓扑。详细考虑了 $^7$Be 核通过 $^7$Be$\rightarrow ^4$He + $^3$He, $^7$Be$\rightarrow$2$^3$He + n 和 $^7$Be$\rightarrow ^4$He + 2$^1$H 通道的解离。研究发现，在通道 $^7$Be$\rightarrow ^4$He + 2$^1$H 中，与通道 $^7$Be$\rightarrow ^6$Be + n 级联衰变 $^6$Be$\rightarrow ^4$He +2p 有关的事件约占 27%。

Fragmentation of 1.2 A GeV $^7$Be nuclei in nuclear photographic emulsion

The charge topology of peripheral fragmentation of 1.2 A GeV $^7$Be nuclei in a nuclear emulsion is presented. The dissociation of $^7$Be nuclei via the channels $^7$Be$\rightarrow ^4$He + $^3$He, $^7$Be$\rightarrow$2$^3$He + n and $^7$Be$\rightarrow ^4$He + 2$^1$H is considered in detail. It is found that in the channel $^7$Be$\rightarrow ^4$He + 2$^1$H, events related to the channel $^7$Be$\rightarrow ^6$Be + n with the cascade decay $^6$Be$\rightarrow ^4$He + 2p account for about 27 %.
