First Measurement of 87Rb(α, xn) Cross Sections at Weak r-process Energies in Supernova ν-driven Ejecta to Investigate Elemental Abundances in Low-metallicity Stars

Observed abundances of Z  ∼ 40 elements in metal-poor stars vary from star to star, indicating that the rapid and slow neutron capture processes may not contribute alone to the synthesis of elements beyond iron. The weak r -process was proposed to produce Z  ∼ 40 elements in a subset of old stars. T...
