Microscopic cluster model of 5H and 5He image Original Research Article

We use the Generator Coordinate Method to investigate the 5H and 5He systems in the hyperspherical formalism. The microscopic wave functions are described by a View the MathML source cluster structure for 5H, and by a mixing of View the MathML source and View the MathML source configurations for 5He. The resonance properties are analyzed with the Analytic Coupling in the Continuum Constant (ACCC) method. For 5H, we find results consistent with the literature, but the ground-state width is lower than in previous works. The calculation suggests J=1/2+ and J=3/2+ states in 5He which correspond to the isobaric analog states of low-lying levels in 5H. A J=1/2+;T=3/2 state is found near Ex=21.3 MeV in 5He, with a width of Γ≈1 MeV.
