New s-process path and its implication to 187Re-187Os nucleo-cosmochronometer

T. Hayakawa, T. Shizuma, T. Kajino +4

We study a new s-process path through an isomer of ${}^{186}$Re to improve a ${}^{187}$Re-${}^{187}$Os nucleo-cosmochronometer. The nucleus ${}^{187}$Re is produced by this new path of $^{…
