TL;DR

This paper introduces a parameter-free proxy-SU(3) model to predict nuclear shapes and B(E2) transition rates, providing a new analytic approach that aligns well with existing theories and experimental data.

Contribution

The paper presents a novel, parameter-free proxy-SU(3) scheme for predicting nuclear shape observables and transition rates, offering an analytic alternative to mean-field theories.

Findings

Predictions of beta and gamma deformation variables match well with other models.

B(E2) transition rates predictions agree with experimental data.

The approach provides a new analytic tool for nuclear structure predictions.

Abstract

Using a new approximate analytic parameter-free proxy-SU(3) scheme, we make predictions of shape observables for actinides and superheavy elements, namely beta and gamma deformation variables, and compare these with predictions by relativistic and non-relativistic mean-field theories. Furthermore, we make predictions for B(E2) transition rates of deformed nuclei and compare these with existing data and predictions of other theoretical approaches.
