List of levels for 149PM

Authors: Balraj Singh and Jun Chen | Citation: Nucl. Data Sheets 185, 2 (2022) | Cutoff date: 23-Aug-2022

¹⁴⁹Pm produced and identified by 1941La01, 1946Bo25, 1947In06, and 1947Ma28, followed by several later studies of its decay

2012Da16 investigated possible α decay of ¹⁵³Eu to the ground state in ¹⁴⁹Pm at the HADES underground laboratory. α lower limit of T_1/2 of 5.5×10¹⁷ y was established for this decay mode, essentially, with no observation of a signal for α decay of ¹⁵³Eu.

Mass measurement: 1975Ka25
