Halo Effective Field Theory of⁶He

Abstract

Abstract.6 He has a cluster structure with a tight 4 He (α) core surrounded by two loosely bound neutrons (n) making it a halo nucleus. The leading-order (LO) Halo Effective Field Theory (EFT) [1, 2] calculations using momentum-space Faddeev equations pertinent to a bound 6 He were carried out in [3]. In this work, we investigate 6 He up to next-to-leading order (NLO) within Halo EFT.
