Promptγ-ray spectroscopy of the neutron-rich¹²⁴Cd

Abstract

Abstract. Prompt -ray spectroscopy of neutron-rich cadmium isotopes has been performed. The nuclei of interest have been populated via a 25-MeV, proton-induced fission of the 238 U thick target and prompt -rays measured using the multi-detector HPGe array JUROGAM II. New high-spin decays have been observed and placed in the level scheme using triple coincidence gates. The experimental results are compared to shell-model calculations and show good agreement.

Evolution of nuclear structure in and around Z = 50 closed shell: Generalized seniority in Cd, Sn and Te isotopes

“…Recent experiments [9] have highlighted a linear behavior of Q−moments for the 11/2 − states of the neutron-rich Cd isotopes even beyond the h 11/2 orbital. This unique simplification of the complex configurations in Cd isotopes has surprised the community [10] and has eventually led to extensive studies of Cd isotopes, from understanding the moments of 11/2 − states and other single-particle states in odd-A nuclei to the B(E2) values of the first excited 2 + states in even-even nuclei [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]. This is in addition to the continuing interest in Cd isotopes since decades, both theoretical and experimental , where they were first labeled as vibrators and then refuted this status by supporting a weakly deformed structure.…”
