The nuclear properties of the 95Nb, 97Mo, 99Mo &102Mo nuclei were studied with the 93Nb(t, p) 95Nb, 95Mo(t, p)97Mo, 97Mo(t, p)99Mo and100Mo(t, p)102Mo reactions. The experiments were carried out using triton beam energy of 12 MeV obtained from tandem Van de Graaff accelerator at the Atomic Weapon Research Establishment, Aldermaston, England. Out going protons were detected in nuclear emulsion plates using a multi-channel magnetic spectrograph. Proton spectra were obtained at 12 different of angles from 50 to 87.50 at an interval of 7.50. Absolute differential cross sections for the levels of different energy range in each nucleus were measured. The angular distributions over an angular range 50 to 87.50 were compared with the theoretical distorted- wave Born approximation calculations (DWBA) to determine L and Jp values. The DWBA program was run for different L transitions from 0 to 5 for levels up to the different excitation energy. Assignments of L values were based on closeness of the DWBA fits to the experimental points.
