Stellar β−-decay Rate of 63Ni and Its Impact on the s-process Nucleosynthesis in Massive Stars

Stellar β−-decay Rate of 63Ni and Its Impact on the s-process Nucleosynthesis in Massive Stars

The β ^− -decay rate of ^63 Ni, an important branching point, affects the subsequent nucleosynthesis in the weak component of the slow-neutron capture process (weak s -process). To evaluate the impact of the uncertainties of stellar lifetime of ^63 Ni on abundances, we calculate the contribution to...
