| Research Abstract |
ssr spectroscopy of the nuclei with mass number A= 100-120 has been carried out at the RIBF accelerator (RIKEN). Among the results, the following two points should be emphasized; (1) The life of nuclei are about 2 times shorter than those obtained by theoretical models. This fact is urging reexamination of the nucleosynthesis scenario. (2) Some excitation states including isomers are first measured, and new knowledge was brought to nuclear shape and structure. Electronics including data acquisition for gamma ray measurements have been improved which makes vary efficient data acqusition possible
