The ³⁰Mg(t, p)³²Mg "puzzle" reexamined

NUCLEAR STRUCTURE ³²Mg; calculated energies and wave-function amplitudes of first three 0+ states, mixing strength required to reproduce the experimental energy of the second 0+ state. Phenomenological three-level mixing model of unperturbed 0p0h, 2p2h, and 4p4h states.

NUCLEAR REACTIONS ³⁰Mg(t, p)³²Mg, E not given; calculated cross-section ratio σ(second 0+)/σ(first 0+) in 2n-transfer reaction using ³²Mg wave-function amplitudes from three-level mixing model calculations. Comparison with experimental data, and resolution of the puzzle resulting from a two-state mixing model.
