Simultaneous Impacts of Nuclear Shell Structure and Collectivity on *b Decay: Evidence from 80Ga49 / R.Li, Yu.G.Sobolev, S.Stukalov, [a.o.] // Physical Review C. – 2025. – Vol. 111, No. 3. – P. P. 034303. – URL: https://doi.org/10.1103/PhysRevC.111.034303.
The Gamow-Teller strength distribution covering the entire 𝛽-decay window, up to 10.312(4) MeV, of 80𝑔+𝑚 Ga was measured for the first time in photofission of UC𝑥 induced by a 50 MeV electron beam. The new data show significant enhancement in the high-energy region with a jump structure. Simultaneously, the 𝛾 deexciting behavior of 𝛽-populated states presents a competition between deexcitation to 2+ 1[𝛽2=0.155(9)] and to 2+ 2[𝛽2=0.0530.008 0.009)] in 80 Ge . To understand these data, we performed a realistic shell-model calculation and systematic analysis of log𝑓𝑡 ratios between precursors' 𝛽 decay to 2+ 2 and to 2+ 1 of Ga isotopes. We conclude that these phenomena evidence simultaneous impacts of nuclear shell structure and collectivity on 𝐵(GT) distribution and therefore the half-life of the precursor.
