Study of nuclear structure properties of some neutron-rich even-even Titanium isotopes

Abstract

The large-scale shell-model calculations have been performed for neutron-rich even-even titanium isotopes by employing two model spaces: pf (I) and fpg_9/2 (II) and various effective interactions. The energy spectra and electromagnetic quantities have been obtained and compared with the available experimental data. The theoretical results on excitation energies and B(E2) values of $2_1^{+}$ state confirm the existence of subshell closure at N = 32 and the absence of subshell closure at N = 34. Besides, the B(E2) and B(M1) values of excited states are also predicted for which experimental data are not available. These predictions may serve as a valuable reference for future experimental comparisons.
