Description
We report on the first spectroscopy study of the very neutron-rich nucleus 1236Mg24 using the direct two-proton knockout reaction 9Be(38Si,36Mg+γ)X at 83 MeV/nucleon. The energy of the first excited 2+ state of 36Mg, E(21+)=660(6) keV, was measured. The magnitude of the partial cross sections to the ground state and the 21+ state is indicative of strong intruder admixtures in the lowest-lying states as suggested by Monte Carlo shell-model calculations
