Microscopic cluster model of 5H and 5He (T=3/2)

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 cluster structure for 5H, and by a mixing of and 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=21.3MeV in 5He, with a width of Γ≈1MeV.
