High spin states of an odd-proton, an odd-neutron, and an even-even rare-earth nucleus have been investigated using the FN Tandem-Superconducting Linear Accelerator facility at Florida State University. Each $\gamma$-$\gamma$ coincidence experiment was performed using all or part of the Pitt-FSU $\gamma$ array consisting of up to 10 escape suppressed high purity germanium (HPGe) detectors. The nucleus $\sp{177}$Ta was produced with the reaction $\sp{170}$Er($\sp{11}$B,4n) at 55 and 60 MeV. From this experiment, 88 new $\gamma$-rays have been assigned to this nucleus. Investigation of normal deformed identical bands and the $h\sb{9/2}$ bandcrossing anomaly were performed. The nucleus $\sp{175}$Ta was produced using the reaction $\sp{170}$Er($\sp{11}$B,6n) at 80 MeV in a further investigation of the $h\sb{9/2}$ anomaly. High spin states of $\sp{170}$Yb and $\sp{171}$Yb were produced using the reaction $\sp{170}$Er($\alpha,xn$) at 40 MeV and 35 MeV, respectively. These experiments resulted in 67 new $\gamma$-rays being assigned to the even-even nucleus, and 110 new $\gamma$-rays being assigned to the odd-A nucleus. Angular correlations have been measured in the determination of level spins. Configuration assignments are made for the rotational structures in terms of single particle Nilsson states, and a detailed Cranked Shell Model (CSM) analysis has been performed in each case. In addition, Projected Shell Model (PSM) calculations are presented and compared with the experimental data. Transition strength ratios have been measured and compared with theory. / Source: Dissertation Abstracts International, Volume: 57-04, Section: B, page: 2645. / Major Professor: Mark A.
