Total absorption gamma-ray spectroscopy study of the β-decay of 186Hg

Physics Letters B, 2021
The Gamow-Teller strength distribution of the decay of 186Hg into 186Au has been determined for the first time using the total absorption gamma spectroscopy technique and has been compared with theoretical QRPA calculations using the SLy4 Skyrme force ...

Searching for Shape Coexistence in \(^{42}\)Ca

Acta Physica Polonica B Proceedings Supplement
Four neutron capture experiments were carried out at the Institut Laue–Langevin (ILL), Grenoble, with the FIPPS \(\gamma \)-ray spectrometer, with the aim of performing a complete low-spin spectroscopy study of \(^{42,43,44,45}\)Ca isotopes. The goal of the project is to investigate the structure of Ca isotopes in the \(A\sim 40\)–48 mass region ...

Shape phase transition and shape coexistence in the Bose-Fermi system

EPJ Web of Conferences, 2018
A classical analysis of shape phase transition and shape coexistence in odd-even nuclei has been carried within the interacting boson-fermion model. The results indicate that shape coexistence can be taken as a signature of shape phase transition in odd ...

Shape transition and shape coexistence in odd-mass nuclei around 100Zr [PDF]

EPJ Web of Conferences
The A = 100 mass region is of special interest due to a rapid shape transition from nearly spherical to strongly deformed shapes by going from neutron number 58 to 60, especially pronounced in the Sr and Zr isotopes. The sudden change of the ground-state

Shape coexistence from lifetime and branching-ratio measurements in 68,70Ni

Physics Letters B, 2016
Shape coexistence near closed-shell nuclei, whereby states associated with deformed shapes appear at relatively low excitation energy alongside spherical ones, is indicative of the rapid change in structure that can occur with the addition or removal of ...

At the borderline of shape coexistence: Mo and Ru

Physical Review C, 2023
Background Even-even isotopes of Mo ($Z=42$) and Ru ($Z=44$) are nuclei close to the subshell closure at $Z=40$, where shape coexistence plays a significant role. As a result, their spectroscopic properties are expected to resemble those of Sr ($Z=38$) and Zr ($Z=40$).

Coexisting shape- and high-K isomers in the shape transitional nucleus 188Pt

Physics Letters B, 2014
A high-spin study of the shape transitional nucleus 188Pt reveals the unusual coexistence of both shape- and K-isomeric states. Reduced B(E2) transition probabilities for decays from these states inferred from the data clearly establish their hindered ...

Sr isotopes: The interplay between shape coexistence and quantum phase transitions [PDF]

EPJ Web of Conferences, 2023
In this contribution we study the even-even Sr isotopes considering the influence of particle-hole intruder states. We find that the rapid onset of deformation at A = 98 and onwards can be explained by the crossing of regular and intruder states.

Shape coexistence in 178Hg

Physical Review C, 2019
Lifetime measurements of excited states in 178 Hg have been performed using the 103 Rh ( 78 Kr , p 2 n ) reaction at a beam energy of 354 MeV. The recoil-decay tagging (RDT) technique was applied to select the 178 Hg nuclei and associate the prompt γ rays with the correlated characteristic ground-state α decay.
