Cross-shell excitations in ⁴⁶Ca studied with fusion reactions induced by a reaccelerated rare isotope beam

NUCLEAR REACTIONS ⁷Li(⁴⁵K, 2nα)⁴⁶Ca, E=4.66 MeV/nucleon, [secondary ⁴⁵K beam from ⁹Be(⁴⁸Ca, X) primary reaction, followed by separation of fragments using A1900 fragment separator at NSCL-MSU]; measured charged-particle recoils, Eγ, Iγ, (particle)γγ-coin using JANUS array of SeGA array of sixteen 32-fold segmented HPGe detectors, and an annular double-sided silicon detector. ⁴⁶Ca; deduced levels, J, π, rotational-like band built on the excited 0+ state, configurations. Comparison with shell-model calculations in the sd-pf-sdg orbital space.
