摘要: Abstract The decay of 143 Sm has been investigated by means a Ge(Li) spectrometer. Levels Pm at 272.9, 1056.6, 1173.3, 1341.0, 1403.5, 1515.7, 1751.3, 1816.8, 2009.6, 2081.2 and 2172.5 keV have established. Gamma-gamma coincidences confirmed the existence 272.9 level. Spin parity assignments for all observed levels suggested from electron capture positon disintegration considerations gamma branches. level is compared with an extreme one-quasi-particle model extended one-plus-three-quasi-particle Tamm-Dancoff approximation.
