The decay of 56-s, ¹⁴⁸Ce to levels of odd–odd ¹⁴⁸Pr

Abstract

The decay of 148 Ce to levels of 148 Pr has been studied using mass-separated sources. A half-life of 56 ± 1 s has been measured for the decay of 148 Ce. A level scheme containing 40 γ rays and 15 excited levels is proposed for 148 Pr. Strongly β-fed 1 + levels have been identified at 390 and 520 keV that are similar in position to 1 + levels observed in isotonic 146 La and isotopic 146 Pr.
