摘要

研究了质量分离、富中子的143Cs (tNU>12 = 1.8 s)和143Ba (tNU>12 = 14.5 s)同位素。用Ge(Li)和Si(Li)探测器分别研究了这些原子核β衰变后的单伽马能谱和转换电子能谱。列出了伽玛射线和内部转换电子的相对强度，并提出了基于跃迁多极化的自旋和宇称赋值。结果与先前的测量结果进行了比较。给出了143Ba中存在等长态的一些证据。

Decay of mass-separated 143Cs and 143Ba

Mass separated, neutron rich $^{143} Cs (t_{NU>12} = 1.8 s)$ and $^{143} Ba (t_{NU>12} = 14.5 s)$ isotopes were studied. 1565 0 Singles gamma and conversion electron spectra following the β- decay of these nuclei were investigated using Ge(Li) and Si(Li) detectors, respectively. Gamma ray and internal conversion electron relative intensities are listed, and spin and parity assignments, based on transition multipolarities, are proposed. Results are compared with earlier measurements. Some evidence for an isometric state in ¹⁴³Ba is presented.
