Abstract
We describe the investigation of high-spin states in Mg populated with the reaction at 62- and 68-MeV beam energy. The excited states were established through the coincident detection of up to four and particles in complete decay cascades toward a final state of angular momentum zero, the ground state of either Ne or O. We describe a new analysis method for the angular correlations in such events and apply it with the goal to assign spin and parity to -unbound states in Mg. We establish a number of high-spin, natural-parity states between spins 6 and 12, including the lowest known and levels. The energy systematics of positive- and negative-parity high-spin states are compared to the predictions of modern shell-model calculations.
