Abstract

The results of investigation of the break-up of some fraction of the fission fragments from the binary fission of ²⁵²Cf(sf), while they pass through the Ti foil are presented. Two experimental approaches add each other in the study namely missing mass and “double-hit” methods. In the frame of the latter one both products of the break-up are detected in the same PIN diode. The break-up occurs after a binary fission and is delayed by approximately 150 ps. This is a strong indication that the fragment undergoing the break-up is born in the shape isomer state.

252Cf（sf）三元衰变的双击实验研究

本文介绍了252Cf（sf）二元裂变中部分裂变碎片通过Ti箔时的破裂情况。两种实验方法在研究中相互补充，即缺失质量和“双击”方法。在后一种框架中，在同一PIN二极管中检测到分裂的两个产物。分裂发生在二元裂变之后，并且延迟了大约150ps。这是一个强有力的迹象，表明经历分裂的碎片是在形状同分异构体状态下诞生的。
