Levels in ('90)Y were studied using the ('91)Zr(t,(alpha))('90)Y and ('89)Y(n,(gamma))('90)Y reactions. The results of these studies were used to locate the members of the (pi)(p1/2)('1) (upsilon)(d5/2)('1), (pi)(g9/2)('1) (upsilon)(d5/2)('1), (pi)(p3/2)('-1) (upsilon)(d5/2)('1), and (pi)(f5/2)('-1) (upsilon)(d5/2)('1) configurations. Of particular interest is the anomalously high energy of the 0- state of the (pi)(f5/2)('-1) (upsilon)(d5/2)('1) multiplet. In addition to this several new low spin levels were discovered in the ('89)Y(n,(gamma))('90)Y reaction. / The structure of ('92)Nb was investigated by the ('91)Zr(('3)He,d)('92)Nb reaction. The members of the (pi)(g9/2)('1) (upsilon)(d5/2)('1) configuration were strongly populated and have spectroscopic factors with simple 2J(,f)+1 structure. Several states are populated with (,p) = 1 angular distributions. Also a large portion of the (,p) = 2 spectroscopic strength is observed to be fragmented over many T(,<) states. / The energy spectra of ('90)Y and ('92)Nb were calculated using finite-range matrix elements including both central and tensor potentials. The tensor force is found to have a large effect on the low spin negative parity states of ('90)Y. / Source: Dissertation Abstracts International, Volume: 41-03, Section: B, page: 1008. / Thesis (Ph.D.)--The Florida State University, 1980.
