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.

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 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.

Shape Coexistence in Even–Even Nuclei: A Theoretical Overview

Atoms, 2023
The last decade has seen a rapid growth in our understanding of the microscopic origins of shape coexistence, assisted by the new data provided by the modern radioactive ion beam facilities built worldwide.

Symmetry and Shape Coexistence in 10Be [PDF]

Bulgarian Journal of Physics, 2022
Within the low-lying spectrum of 10Be, multiple rotational bands are found, with strikingly different moments of inertia. A proposed interpretation has been that these bands variously represent triaxial rotation and prolate axially-deformed rotation. The bands are well-reproduced in ab initio no-core configuration interaction (NCCI) calculations.

To Shell Model, or Not to Shell Model, That Is the Question

Physics, 2022
The present review takes steps from the domain of the shell model into open shell nuclei. The question posed in the title is to dramatize how far shell model approaches, i.e., many nucleons occupying independent-particle configurations and interacting ...

The spatial configuration of biotic interactions shapes coexistence-area relationships in an annual plant community

Nature Communications, 2021
Local patterns of species coexistence across scales could determine the shape of species-area relationships. Here the authors apply a structuralist approach to empirical data on annual plant communities to assess how species interactions shape ...

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

Shape Coexistence In Light Krypton Isotopes [PDF]

AIP Conference Proceedings, 2005
Coexisting states of prolate and oblate shapes were studied via Coulomb excitation of radioactive 74Kr and 76Kr beams at safe energies at GANIL. The results for the transitional E2 matrix elements for several yrast transitions in both isotopes are in contradiction with the B(E2) values extracted from the lifetimes that are found in the literature.
