Shell model analysis of the B(E2, 2+ → 0+) values in the A = 70, T = 1 triplet 70Kr, 70Br, and 70Se

The B(E2, 2+ → 0+) transition strengths of the T = 1 isobaric triplet 70Kr, 70Br, 70Se, recently measured at the RIKEN Radioactive Isotope Beam Factory (RIBF), are discussed in terms of state-of-the-art large scale shell model calculations using the JUN45 and JUN45+LNPS plus Coulomb interactions. In...
