High-spin states in 46Ti have been investigated with the reaction 28Si(24Mg,α2p) at 100 MeV, using the GASP γ-ray array and the charged-particle detector ISIS. The positive parity yrast sequence has been observed up to the 14+ terminating state and several high-energy transitions have been established above the termination state. Both the signatures of a negative parity band have been observed up to the 16- and 17- terminating states, plus one more transition from an 18- state at 19.086 MeV excitation. The observed states are interpreted within the frame of large scale shell model calculations in the full pf space (positive parity) and as particle-hole excitations from the d3/2 shell (negative parity).

Abstract
High-spin states in 46Ti have been investigated with the reaction 28Si(24Mg,α2p) at 100 MeV, using the GASP γ-ray array and the charged-particle detector ISIS. The positive parity yrast sequence has been observed up to the 14+ terminating state and several high-energy transitions have been established above the termination state. Both the signatures of a negative parity band have been observed up to the 16- and 17- terminating states, plus one more transition from an 18- state at 19.086 MeV excitation. The observed states are interpreted within the frame of large scale shell model calculations in the full pf space (positive parity) and as particle-hole excitations from the d3/2 shell (negative parity).Pubblicazioni consigliate
