Abstract
Lifetimes of the excited states in the neutron-rich Ti-52,Ti-54 nuclei, produced in a multinucleon-transfer reaction, were measured by employing the Cologne plunger device and the recoil-distance D ...
Highlights
The B(E 2) values for 52Ti determined in this work are in disagreement with the known data, but are consistent with the predictions of the shell-model calculations and reduce the previously observed pronounced staggering across the even-even titanium isotopes
Understanding the evolution of shell structure toward the drip lines is one of the driving forces for many theoretical and experimental efforts, as investigations have shown that the shell structure often changes significantly as a result of the rearrangement of single-particle levels in exotic nuclear regions [1]
Studies of neutron-rich Ti isotopes are essential for an understanding of the shell structure in the Ti-Cr-Fe region beyond N = 28 and toward Z = 20
Summary
Understanding the evolution of shell structure toward the drip lines is one of the driving forces for many theoretical and experimental efforts, as investigations have shown that the shell structure often changes significantly as a result of the rearrangement of single-particle levels in exotic nuclear regions [1]. In this context, the N = 40 island of inversion represents a rich testing ground. The experimental data assisted a comprehensive description of these nuclei with respect to the high collectivity predicted using the modern shell-model calculations [2,6]. The collective structure in 58Fe evolves to a neutron-subshell closure along the isotonic chain with decreasing proton number, i.e., from
