Collective properties of deformed atomic clusters described within a projected spherical basis

TL;DR

This paper presents a unified model using projected spherical states to study properties of Na clusters, effectively describing both spherical and deformed clusters and explaining photoabsorption spectra with RPA.

Contribution

It introduces a projected spherical basis for modeling atomic clusters, bridging spherical and deformed cases within a single framework.

Findings

Successfully describes spherical and deformed Na clusters

Realistically reproduces photoabsorption cross sections

Uses RPA with Schiff dipole moment as transition operator

Abstract

Several relevant properties of the Na clusters were studied by using a projected spherical single particle states.The proposed model is able to describe in an unified fashion the spherical and deformed clusters. Photoabsorbtion cross section is realistically explained within an RPA approach and a Shiff dipole moment as a transition operator
