Constraints for stellar electron-capture rates on ${}^{86}$Kr via the ${}^{86}$Kr($t$,${}^3$He$+\gamma$)${}^{86}$Br reaction and the implications for core-collapse supernovae

R. Titus, E. M. Ney, R. G. T. Zegers +20

In the late stages of stellar core-collapse, prior to core bounce, electron captures on medium-heavy nuclei drive deleptonization and simulations require the use of accurate reacti…
