Abstract

A recent Coulomb excitation study has called into question the 4⁺ spin assignment of the 1414-keV level in ²³²Th, which had earlier been interpreted as a two-phonon γ-vibrational excitation, and had suggested instead a 3^- assignment. Data obtained in the present neutron scattering study of ²³²Th are inconsistent with the 3^- suggestion and support an I ^π = 4⁺ assignment for the 1414-keV level, lending credence to the argument that it is a Kπ = 4⁺ band head.
