Shape coexistence in 66Se

Physics Letters B, 2023
The nuclear structure of 66Se, nucleus beyond the N=Z line on the proton-rich side of the valley of stability, was investigated by the neutron knock-out reaction 67Se(12C,X)66Se using a 12C target.

A mechanism for shape coexistence [PDF]

EPJ Web of Conferences, 2021
The phenomenon of shape coexistence in a nucleus is about the occurence of two different nuclear states with drastically different shapes, lying close in energy.

Microscopic origin of shape coexistence in the N=90, Z=64 region

Physics Letters B, 2022
A microscopic explanation of the nature of shape coexistence in the N=90, Z=64 region is suggested, based on calculations of single particle energies through standard covariant density functional theory. It is suggested that shape coexistence in the N=90

β-decay studies for shape coexistence

Frontiers in Physics
β decay has played a key role in studies of shape coexistence throughout the nuclear chart. This has been mainly due to the sensitivity in γ-ray and conversion electron spectroscopy that can be achieved following the population of excited states by β ...

Evidence for shape coexistence and superdeformation in 24Mg

Physics Letters B, 2020
The E0 transition depopulating the first-excited 0+ state in 24Mg has been observed for the first time, and the E0 transition strength determined by electron-positron pair and γ-ray spectroscopy measurements performed using the Super-e pair spectrometer.

Shape Coexistence in Odd-Z Isotopes from Fluorine to Potassium

Particles
The shape of a nucleus is one of its fundamental properties. We conduct a systematic investigation of shape coexistence in odd-Z nuclei from fluorine to potassium using the deformed relativistic Hartree–Bogoliubov theory in continuum. First, we present a

Extreme shape coexistence observed in 70Co

Communications Physics
The shape of the atomic nucleus is a property that underpins our understanding of nuclear systems, impacts the limits of nuclear existence, and enables probes of physics beyond the Standard Model.

Shape coexistence and mixing of low-lying 0+ states in 96Sr

Physics Letters B, 2018
The low energy excited 02,3+ states in 96Sr are amongst the most prominent examples of shape coexistence across the nuclear landscape. In this work, the neutron [2s1/2]2 content of the 01,2,3+ states in 96Sr was determined by means of the d(95Sr, p ...

Shape Evolution and Coexistence in Neutron-Rich Yb, Hf, W, Os, and Pt Nuclei [PDF]

Journal of Nuclear Research and Applications, 2023
We have investigated the shape evolution and shape coexistence in the even-even neutron-rich isotopes of Yb, Hf, W, Os, and Pt and the isotones N = 110-122 in the A~190 within the microscopic-macroscopic Cranked Nilsson-Strutinsky framework.
