Properties of low-lying states in Z≈50 nuclei have been in the focus of both experimental and theoretical communities to systematically investigate the evolution of nuclear features, from neutron-deficient to neutron-rich cases.
While in the neutron-rich Sn and Te nuclei the excitation energy of the $2^+_1$ and $4^+_1$ levels and the B(E2;$2^+_1 \to 0^+_{g.s.}$) values have traditionally...
The long isotopic chains with $Z$ around 50 serve as good testing grounds for nuclear models studying the evolution of shell structure and interplay between pairing and quadruple correlations. The Cd isotopes have only two proton holes below the Z = 50 shell, being expected to show similar features with Sn nuclei except for the larger collectivity. The comparison of B($E2;2^+_1 \rightarrow...
Abstract: We propose to measure lifetimes of excited states in A~90 nuclei between N=Z and the closed neutron shell at N=50 using the Recoil Distance Doppler Shift (RDDS) technique. Level lifetimes of low-lying yrast states in this region of the nuclear chart are sensitive to the competition between isovector pairing forces resulting in seniority symmetry, isoscalar correlations, and the...
