Effects of s-process branchings on stellar and meteoritic abundances

Creators

Description

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 148Pm/sup g,m/ are in thermal equilibrium during the s-process. The branch at 148Pm then leads to an inferred s-process neutron density of 3 x 108 cm-3
