Abrupt structural transition in exotic molybdenum isotopes unveils an isospin-symmetric island of inversion

NUCLEAR REACTIONS ⁹Be(⁸⁶Mo, ⁸⁴Mo), E=103 MeV/nucleon; measured reaction products, Eγ, Iγ. ^84,86Mo; deduced γ-ray energies, level T_1/2, B(E2) systematics. Comparison with quasi/pseudo-SU(3) estimates (QPSU3) and Projected Hartree-Fock solutions (PHF) for different np-nh configurations, DNO shell-model calculations (DNO-SM), shell-model diagonalization (SM), and experimental values.
