Role of spd- Continuum Components in the Halo Nucleus 6He

TL;DR

This paper investigates how various continuum components influence the structure of the weakly bound nucleus 6He, revealing its collective nature and the contributions of multiple configurations to its ground state.

Contribution

It introduces a method to analyze the role of unbound spd-waves in 6He using pairing interactions, highlighting the collective behavior from multiple continuum states.

Findings

6He ground state exhibits collective nature from five continuum configurations.

Contributions from s, p, and d wave components are essential for its structure.

Ground state properties are successfully calculated using this approach.

Abstract

Role of different continuum components in the weakly bound nucleus 6He is studied by coupling unbound spd-waves of 5He by using simple pairing contact-delta interaction. The results show that 6He ground state $0^+$ displays collective nature by taking contribution from five different oscillating continuum states that sum up to give an exponentially decaying bound wavefunction emerging from five different possible configurations i.e. $(s_{1/2})^2$, $(p_{1/2})^2$, $(p_{3/2})^2$, $(d_{3/2})^2$ and $(d_{5/2})^2$. The ground state properties of 6He has been calculated.
