Atomic corrections for the unique first forbidden $\beta$ transition of ${}^{187}$Re

O. Niţescu, R. Dvornický, F. Šimkovic

In this paper, we reexamine one of the most promising candidates for determining the neutrino mass scale -- the unique first forbidden $\beta$ transition from ${}^{187}$Re($5/2^{+}$) to $^…
