Abstract : The beta decay of 143Sm was reinvestigated with the aid of a Ge(Li) detector. Levels of 143Pm at 271.8, 1,056.5, 1,173.4, 1,342.1, 1,403.2, 1,514.9, 1,752.8, 1,816.3, 1,853.6, (2,000), 2,009.0, 2,080.5, 2,344, 2,443, 2,463, 2,906 and (3,054) keV were established. Log ft values for all observed beta transitions have been calculated. Spin and parity assignments have been made from electron capture and positon disintegration considerations and gamma branches. The experimental level scheme of 143Pm is compared with the results of 1 and 3 q.p. calculations for N = 82 nuclei. (Author)
