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

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.
