The level scheme and electromagnetic properties of 148Pm have been studied using 149Sm(d, 3He) and 148Nd(p, nγ) reactions. Combining these measurements with estimates for E2/M1 decay branching ratios leads to the tentative conclusion that 148Pmg,m are in thermal equilibrium during the s-process. The branch at 148Pm then leads to an inferred s-process neutron density of 3 × 108 cm−3.
