The nuclear structures of $\sp{143}$Nd and $\sp{145}$Sm were investigated using the techniques of $\gamma$-ray and conversion electron spectroscopy. Level schemes were established for $\sp{143}$Nd and $\sp{145}$Sm using data obtained from $\gamma-\gamma$ coincidence, angular distribution and conversion electron experiments. / The $\sp{143}$Nd nucleus was produced from the heavy-ion fusion-evaporation reaction $\sp{130}$Te($\sp{18}$O, 5n) at a beam energy of 85 MeV. A total of 46 new transitions and 27 new levels, which range from 3.6 MeV to 10.8 MeV in excitation energy, were placed in the level scheme of $\sp{143}$Nd. / The reaction $\sp{138}$Ba($\sp{12}$C, 5n) at a beam energy of 76 MeV was used in producing the $\sp{145}$Sm nucleus. The level scheme includes 22 new $\gamma$-rays and $\gamma / Tentative spins assignments were made to new states in both nuclei from DCO ratios extracted from $\gamma-\gamma$ coincidence data. Angular distribution and conversion electron measurements were used in confirming previous spin and parity assignments. / The spectra are discussed in the framework of the weak coupling model and the empirical shell model. The weak coupling interpretation of $\sp{145}$Sm predicts the presence of a 10$\sp+$ state near 3.9 MeV in $\sp{144}$Sm. / Source: Dissertation Abstracts International, Volume: 56-11, Section: B, page: 6194. / Major Professor: Paul D.
