matrix elements for the quintuplet of states in 49Ti, centered on the 2+ core excitation,
was measured for the first time, using the CLARION2-TRINITY arrays [1]. A total of
nine E2 matrix elements are reported, four of which were previously unknown. 49Ti shows a 20% quenching in electric quadrupole transition... -

First-order electromagnetic processes are the primary mechanism by which excited states in atomic nuclei relax, most-often via single γ-ray emission. Since both the initial- and final-state wave functions possess a well-defined spin and parity, conservation laws impose a characteristic multipolarity for each discrete transition. Nature favours pathways that proceed via the lowest- available...

the excited states of the exotic proton-rich nucleus 55Cu. We could study such nucleus,
characterized by an isospin T=3/2, using in-beam γ-ray spectroscopy, despite it is un-
bound, lying beyond the proton dripline. The study exploited three distinct reaction
mechanisms: inelastic excitation, single... -

collectivity, we studied the rare isotopes 74,76Kr and 72Se, as well as stable 74Se via (p, p′) and (p, 2p) reactions in inverse kinematics with GRETINA, the S800, and the NSCL-Ursinus LH2 target [1, 2, 3]. Our work...
