We studied the charge radius, rms radius and neutron skin thickness ∆r np in even-even isotopes of Si, S, Ar and Ca and isotones of N =20, 28, 50 and 82. The ∆r np in doubly-magic 48 Ca, 68 Ni, 120,132 Sn and 208 Pb nuclei has also been calculated. Theoretical calculations are done with the Hartree-Fock-Bogoliubov theory with the effective Skyrme interactions. Calculated theoretical estimates are in good agreement with the recently available experimental data. The charge radii for Si, S, Ar and Ca isotopes is observed to be minimum at neutron number N =14. The theoretically computed results with UNEDF0 model parameterization of functional are reasonably reproducing the experimental data for ∆r np in 48 Ca, 68 Ni and 120,132 Sn. The energy density functional of UNEDF1 model provides much improved result of ∆r np for 208 Pb.

“…Shape and configuration coexistence in the neutronrich sulfur isotopes has attracted much attention, with results showing a strong competition among different configurations as well as fairly large collectivity observed in even-even 40,42,44 S isotopes [4,[7][8][9]. The collective nature of 44 S at N = 28 was evidenced from the low-lying 2 + state and large B(E2) reduced transition probability [4].…”

“…The experiment was performed at the Coupled Cyclotron Facility at the National Superconducting Cyclotron Laboratory (NSCL). The secondary beam of 44 Cl was produced from the fragmentation of a 140-MeV/nucleon 48 Ca primary beam impinging on a 9 Be production target and was separated in the A1900 fragment separator [23]. The secondary beam was used to populate 43 S via proton knock-out reactions.…”

Lifetime Measurements and Triple Coexisting Band Structure in S43

Lifetime measurements of excited states in the neutron-rich nucleus ^{43}S were performed by applying the recoil-distance method on fast rare-isotope beams in conjunction with the Gamma-Ray Energy Tracking In-beam Nuclear Array. The new data based on γγ coincidences and lifetime measurements resolve a doublet of (3/2^{-}) and (5/2^{-}) states at low excitation energies. Results were compared to the π(sd)-ν(pf) shell model and antisymmetrized molecular dynamics calculations. The consistency with the theoretical calculations identifies a possible appearance of three coexisting bands near the ground state of ^{43}S: the K^{π}=1/2^{-} band built on a prolate-deformed ground state, a band built on an isomer with a 1f_{7/2}^{-1} character, and a suggested excited band built on a newly discovered doublet state. The latter further confirms the collapse of the N=28 shell closure in the neutron-rich region.

“…As detailed in Ref. [29], for the even-mass S isotopes, the evolution of the yrast sequence was discussed in terms of E(6 + )/E(2 + ) and E(4 + )/E(2 + ) energy ratios. For 42 S, a candidate for the 2 + 2 state could be proposed that displays a unique decay branching as compared to the lighter 38,40 S. This was shown to be rooted in its neutron single-particle structure and confirmed by the SDPF-MU shell-model calculations.…”

The nuclear potential and resulting shell structure are well established for the valley of stability, however, dramatic modifications to the familiar ordering of single-particle orbitals in rare isotopes with a large imbalance of proton and neutron numbers have been found: new shell gaps emerge and conventional magic numbers are no longer valid. This article outlines some of the recent in-beam γ-ray spectroscopy measurements at NSCL aimed at shedding light on the evolution of nuclear structure around neutron number N = 28 in neutron-rich Ar and S isotopes.
