DEFORMED INTRUDER BANDS IN SN-113

High-spin states in the odd-A Sn-113 nucleus have been investigated wi th the Mo-100(O-18, 5n) reaction at 94 MeV using the Chalk River 8 pi array. Three decoupled (Delta I=2) rotational bands extending to spins I in the range (63/2-69/2)(h) over bar have been identified and conne cted to known low-lying states. Experimental observations for the most extended band have been interpreted as evidence for smooth band termi nation. Theoretical calculations performed within a configuration-depe ndent shell-correction approach suggest that all three bands are built upon deformed two-particle-two-hole proton excitations across the Z = 50 shell gap.
