Title: Structure of odd- $A$ Pt isotopes along the line of stability

Abstract

The structure of the odd-A isotopes ^193,195,197Pt, which lie along the line of stability, has been studied up to high spin through multinucleon transfer reactions. Positive- and negative-parity sequences in Pt-^193,195Pt have been considerably extended and multiple band crossings established. An isomer with T_1/2 = 5.0(5) ns and I^π = 25/2^- is present in ¹⁹⁵Pt. Additionally, the isotopes ^193,195Pt are characterized by moderate oblate deformation, and angular momentum generation at high spin in the yrast, positive-parity sequences is attributed to the rotation alignment of i_13/2 neutrons and h_11/2 protons. Lastly, a detailed understanding of the observed features is presented using calculations based on tilted axis cranking covariant density functional theory as well as others with the ULTIMATE CRANKER code.

Decoupled and semi-decoupled bands in ${}^{197}{Hg}$ and ${}^{199}{Hg}$

Journal Article Negi, D. ; Tandel, S. K. ; Chauhan, P. ; ... - Physical Review C

Here, the structure of decoupled positive-parity and semidecoupled negative-parity bands up to high spin in ^197,199Hg has been studied using multinucleon transfer reactions with the Gammasphere array. A positive-parity band in ¹⁹⁹Hg with the (vi_13/2)³ decoupled configuration that deexcites to levels in the negative-parity sequences is newly established. The semidecoupled sequences in both isotopes are extended to higher spin. Rotation-aligned angular momenta and crossing frequencies determined from experiment are in fair agreement with those from cranking calculations. Finally, a transition from oblate collective rotation at low spin to triaxial noncollective shapes at high spin is indicated.

Nanosecond isomers and the evolution of collectivity in stable, even-A Hg isotopes

Journal Article Suman, Saket ; Tandel, S. K. ; Kumawat, Ankit ; ... - Physical Review C

Isomeric states and associated collective structures have been studied up to high spin in ^198,200,202Hg using multinucleon transfer reactions and the Gammasphere array. A coupled rotational band, with possible four-quasiparticle character, is established in ¹⁹⁸Hg. Sequences built on two-quasiparticle, positive- and negative-parity levels are assigned to ²⁰²Hg. New isomers in ²⁰²Hg with I^π = (7^–) and (9^–), and T_1/2 = 10.4(4) ns and 1.4(3) ns, respectively, have been identified. A half-life of 1.0(3) ns is established for the I^π = 12⁺ state in ²⁰⁰Hg.

Successive neutron alignments in the yrast, negative-parity band of oblate-deformed Tl 199

Journal Article Suman, Saket ; Tandel, S. K. ; Wahid, S. G. ; ... - Physical Review. C

The negative-parity band structure built on the proton h_9/2 state in ¹⁹⁹Tl has been established up to an excitation energy of 7 MeV and spin of (51/2) ℏ. The level scheme has been extended with the inclusion of fourteen new transitions de-exciting levels at high spin. The ΔI = 1 γ rays are found to be more prominently visible in the spectra when comparing to Δ I = 2 transitions. Rotation alignments are evident at frequencies of 0.22 and 0.30 MeV with both being attributed to the breaking of pairs of neutrons in the i_13/2 subshell. Since ¹⁹⁹Tl is expectedmore »« less

Multistep Coulomb excitation of Ni 64 : Shape coexistence and nature of low-spin excitations

Journal Article Little, D. ; Ayangeakaa, A. D. ; Janssens, R. V. F. ; ... - Physical Review. C

The structure of ⁶⁴Ni, the heaviest stable Ni isotope, has been investigated via high-statistics, multistep safe Coulomb excitation to search for shape coexistence, a phenomenon recently observed in neutron-rich ⁶⁶Ni and ⁷⁰Ni as well as in doubly magic, N = 40, ⁶⁸Ni. The study was motivated by recent, state-of-the-art Monte Carlo shell-model calculations (MCSM), where a Hamiltonian with effective interactions incorporating the monopole tensor force predicts the existence of shape coexistence, also in the lower-mass ^62,64Ni isotopes. A set of transition and static E2 matrix elements for both yrast and near-yrast structures was extracted from the differential Coulomb excitation cross sections. From comparisons between the new results and MCSM as well as other shell-model calculations, a clearer picture of the structure of ⁶⁴Ni emerges. Specifically, the low-spin states are shown to be dominated by proton and neutron excitations mainly within the fp shell, with minimal contribution from the g_9/2 shape-driving neutron orbital. The agreement between experimental data and MCSM results indicates a small oblate deformation for themore »« less
