Abstract
High-spin states in the near proton-dripline nucleus Sb-107 have been ident ified, and collectivity in this nucleus has been observed for the first tim e in the form of two rotational bands. One of the observed rotational struc tures is a Delta I = 1 band, and is interpreted as based on a pi(g(9/2))(-1 ) x pi(g(7/2)d(5/2))(2) proton configuration. A second structure has Delta I = 2 character, and is explained as being based on pi h(11/2) x [pi(g(9/2) )(-2) x pi(g(7/2)d(5/2))(2)] proton configuration through comparison with c ranked Nilsson-Strutinsky model calculations. The calculations predict that this band terminates at a spin of 79/2 (h) over bar.
