In this work, the effects of neutron-induced fissile isotopes of Uranium, particularly; Uranium-233 and Uranium-235 are studied using the Coupled-Channelled Optical Model code (OPMAN) code up to 20 MeV. The high demand for nuclear reactor fuels has necessitated this research. As one of the major naturally occurring radionuclides with lots of fuel prospect, Uranium-233 occurred in trace while Uranium-235 occur in 0.71%. Two steps process away from Uranium-233 and Uranium-235 on neutron capture can produce fissile materials to be used as reactor fuel. Though, Uranium-233 and Uranium-235 are not by them self a fissile material, but they are breeder reactor fuels. Computations were done for both the Potential Expanded by Derivatives (PED) which account for the Rigid-Rotor Model (RRM) that treat nuclei as rigid vibrating sphere as well as account for nuclear volume conservation and Rotational Model Potentials (RMP) which account for the Soft-Rotator Model (SRM) that treat nuclei as soft rotating spherical deformed shapes. Each of the calculated data was compared with the retrieved data from Evaluated Nuclear Dada File (ENDF) which was found to be in good agreement. The threshold energies in all cases were found to be 4 MeV for both PED (Potential Expanded by Derivatives) and RMP (Rotational Model Potentials). It is observed that results from RMP much better agreed with the retrieved data than one obtained from PED.

The comparative analysis of the excitation function of Uranium-238 was carried out using a Coupled-Channeled Optical Model code, OPTMAN. The high demand for nuclear reactor fuels has necessitated this research. As one of the major naturally occurring radioisotope of Uranium with lots of fuel prospect, Uranium-238 occur in large quantities (99%). Two steps process away from Uranium-238 on neutron capture can produce fissile materials to be used as reactor fuel. Though, Uranium-238 is not by itself a fissile material. But, it is a breeder reactor fuel. Computations were done for both the Potential Expanded by Derivatives (PED) which account for the Rigid-Rotor Model (RRM) that treat nuclei as rigid vibrating sphere as well as account for nuclear volume conservation and Rotational Model Potentials (RMP) which account for the Soft-Rotator Model (SRM) that treat nuclei as soft rotating spherical deformed shapes.

The radioelement Technetium (element 43) pertains to various domains including the nuclear enterprise (i.e., spent nuclear fuel (SNF) reprocessing and nuclear waste remediation) and nuclear medicine (i.e., development of new imaging agents) as well as to the fundamental science of transition metals (i.e., chemical trends in catalytic properties). One method that can provide critical information to improve knowledge in these domains is 99 Tc nuclear magnetic resonance (NMR) spectroscopy. The review, presented here, summarizes the pivotal role of 99 Tc NMR spectroscopy over the past two decades and presents prospects of the method to tackle challenges in Tc chemistry.
