DECAY CHARACTERISTICS OF PM146,
Abstract
The half-life of Promethium-146 was determined to be 2020 plus or minus 18 days. The radionuclide was produced by a (p,n) reaction on enriched Nd146. The decay of the purified Pm146 was followed on both beta-ray and gamma-ray counters. The gamma-ray energies were determined from pulse-height distribution curves obtained with a Ge(Li) detector. Prominent gamma-rays with energies of 453, 736 and 747 kev and low abundance gamma-rays with energies of 146, 589, 634 and 1189 kev were observed. (Author)
