Title: Theoretical studies of possible toroidal high-spin isomers in the light-mass region

Abstract

We review our theoretical knowledge of possible toroidal high-spin isomers in the light mass region in 28≤A≤52 obtained previously in cranked Skyrme-Hartree-Fock calculations. We report additional toroidal high-spin isomers in ⁵⁶Ni with I=114ℏ and 140ℏ, which follow the same (multi-particle) (multi-hole) systematics as other toroidal high-spin isomers. We examine the production of these exotic nuclei by fusion of various projectiles on ²⁰Ne or ²⁸Si as an active target in time-projection-chamber (TPC) experiments.

PARTICLE-HOLE NATURE OF THE LIGHT HIGH-SPIN TOROIDAL ISOMERS

Conference Staszczak, A. ; Wong, Cheuk-Yin

Nuclei under non-collective rotation with a large angular momentum above some threshold can assume a toroidal shape. In our previous work, we showed by using cranked Skyrme Hartree Fock approach that even even, N = Z, high-K, toroidal isomeric states may have general occurrences for light nuclei with 28 < A < 52. We present here some additional results and systematics on the particle-hole nature of these high-spin toroidal isomers.

A region of high-spin toroidal isomers

Journal Article Staszczak, Andrzej ; Wong, Cheuk-Yin - Physics Letters B

The combined considerations of both the bulk liquid-drop-type behavior and the quantized angular momentum reveal that high-spin toroidal isomeric states may have general occurrences for light nuclei with 28 ≤ A ≤ 52. High-spin N=Z toroidal isomers in this mass region have been located theoretically using cranked self-consistent constraint Skyrme–Hartree–Fock model calculations.

Shape coexistence and high spin states in {sup 52}Cr

Journal Article Kumar, Rajesh ; Chamoli, S K ; Govil, I M ; ... - Physical Review. C, Nuclear Physics

High spin states in {sup 52}Cr have been populated by means of the reaction {sup 27}Al({sup 28}Si,3p){sup 52}Cr at a beam energy of 70 MeV and studied with an array, consisting of eight Compton-suppressed clover germanium detectors. Eleven new {gamma} rays have been assigned to {sup 52}Cr and placed in the level scheme. The level structure of {sup 52}Cr has been extended up to E{sub x}{approx_equal}10 MeV. Spins and parities have been assigned to many of the levels on the basis of directional correlations and linear polarization measurements. The band structures are discussed in the framework of cranked Woods-Saxon andmore »« less

Shell model and mean-field description of band termination in the A{approx}44 nuclei

Journal Article Zalewski, M ; Zdunczuk, H ; Satula, W ; ... - Physical Review. C, Nuclear Physics

We study nuclear high-spin states undergoing the transition to the fully stretched configuration with maximum angular momentum I{sub max} within the space of valence nucleons. To this end, we perform a systematic theoretical analysis of non-fully-stretched I{sub max}-2 and I{sub max}-1 f{sub 7/2}{sup n} seniority isomers and d{sub 3/2}{sup -1}f{sub 7/2}{sup n+1} intruder states in the A{approx}44 nuclei from the lower-fp shell. We employ two theoretical approaches: (i) the density functional theory based on the cranked self-consistent Skyrme-Hartree-Fock method, and (ii) the nuclear shell model in the full sdfp configuration space allowing for 1p-1h cross-shell excitations. We emphasize the importancemore »« less
