摘要

用ＨｐＧｅ探测器和低本底康普顿抑制谱仪研究了１３５Ｌａ的放射性衰变，实验得到单谱、康普顿抑制谱和γ－γ符合谱。根据实验数据得到１３５Ｂａ低激发态、γγ跃迁的能量、强度和级联关系以及１３５Ｌａ衰变纲图。采用了角动量投影壳模型理论对１３５Ｂａ低激发态能级进行计算，并与实验值进行了比较。

Abstract

The radioactive decay of 135La has been studied with the aid of a low background Compton suppression spectrometer and HPGe detectors.The single spectra

Compton suppressed spectra and r-r coincidence spectra were measured.The energies

intensities and cascade relations of r-rays from low excited levels were obtained and the decay scheme of 135La was deduced. The levels of low excited states were calculated using the angular momentum projected shell model(PSM) and compared with experimental values.
