Simultaneous impacts of nuclear shell structure and collectivity on $\beta$ decay: Evidence from ${}^{80}$Ga${}_{49}$

R. Li, D. Verney, G. De Gregorio +32

The Gamow-Teller strength distribution covering the entire $\beta$-decay window, up to 10.312(4) MeV, of ${}^{80g+m}$Ga was measured for the first time in photo fission of UC${}_x$ induced…
