The level scheme and electromagnetic properties of /sup 148/Pm have been studied using /sup 149/Sm(d,/sup 3/He) and /sup 148/Nd(p,n..gamma..) reactions. Combining these measurements with estimates for E2/M1 decay branching ratios leads to the tentative conclusion that /sup 148/Pm/sup g,m/ are in thermal equilibrium during the s-process. The branch at /sup 148/Pm then leads to an inferred s-process neutron density of 3 x 10/sup 8/ cm/sup -3/.
