Abstract

Excited states in Mo92 are populated via the Y89(Li6,3n)Mo92 reaction at the tandem of XTU, INFN-LNL. The level scheme of Mo92 is revised and expanded considerably by the γ-γ coincidence measurement. The newly observed level structures are compared with different shell-model calculations performed in various model spaces. The results show that the several high-energy (≈2 MeV) transitions, observed for the first time in the current work, could be a presumable signature of N=50 core-breaking effect. The measured strengths of E1 transitions between the low-lying positive and negative bands indicate an important contribution from Z=28 proton core-excitation.
