List of levels for 153PM

Author: N. Nica | Citation: Nucl. Data Sheets 170, 1 (2020) | Cutoff date: 16-Aug-2020

E(level): From least-squares fit to gamma-ray data from ¹⁵³Nd β- decay and ²⁵²Cf SF datasets, otherwise from average of values from transfer reaction studies

E(level): From total absorption γ-ray spectrometer measurements, it is known that there several other levels weakly fed in the ¹⁵³Nd β- decay. However, since the number of levels and their energies are not determined, they are not included here.

J^π(level): Unless otherwise noted, the Jπ are from L values and analyzing powers in (pol t,α) and L values from (d,³He). For levels from ²⁵²Cf SF dataset, tentatively assigned in 2018Bh07 from band assignments and systematics of odd-A Pm isotopes

T_1/2(level): From ¹⁵³Nd β- decay (1992TaZN) for excited levels.
