Proton-electron, proton-gamma, and proton-gamma-gamma coincidence techniques have been used to study excited state transitions in even-even nuclei in the mass 100 region produced in the (t,p) reaction (E(,t) = 16 MeV). Using the (t,p) proton-gamma-gamma coincidence method, we have established five new levels in ('112)Pd and 3 new levels in ('102)Mo. Our discovery of a possible 10('+) level in ('102)Mo would be, if confirmed, the first physical evidence of a back-bending anomaly in the mass 100 region. Using the simultaneous proton-electron and proton-gamma coincidence methods, EO transitions in ('100)Mo, ('102)Mo, ('106)Ru, ('108)Pd, ('110)Pd, and ('112)Pd have been observed. Branching ratios for these EO transitions have been used to calculate the X(,ijk) and (rho)('2)(,ij) values for a number of transitions of the type O(,i)('+) - O(,f)('+) in these nuclei. / The results of our measurements are discussed in terms of current nuclear models. The back-bending anomaly at J('(pi)) = 10('+)in ('102)Mo confirms earlier theoretical predictions of such an anomaly. Level systematics in the Pd isotopes, particularly those of excited O('+) states, are in general agreement with the proton intruder orbital picture used to describe Cd nuclei. The systematics of monopole strengths in the Mo isotopes agree with the picture of a subshell proton intruder configuration. / Source: Dissertation Abstracts International, Volume: 47-06, Section: B, page: 2432. / Thesis (Ph.D.)--The Florida State University, 1986.
