Single-step Coulomb excitation of 46,48,49,50Ti is presented. A complete set of E2
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...
Using radioactive beams provided by the RIBF facility, Riken, Tokyo, Japan, we explored
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...
To investigate the microscopic configurations causing the prolate-oblate-triaxial shape
transition near A = 72 and their possible influence on octupole as well as hexadecapole
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...
