This thesis describes the experimental investigation of the excited states of 26Mg below 11 MeV excitation energy by the technique of inelastic electron scattering. The experiment was performed using the 120 MeV electron linear accelerator situated at the Kelvin Laboratory. The general features of electron scattering as a technique for investigating nuclear structure and the nuclear properties measured by elastic and inelastic experiments are discussed. A comparison with the nuclear properties measured by other electromagnetic techniques is also given. The previous studies of 26Mg are reviewed and the objectives of the present experiment are logically derived. The relevant formalism of electron scattering is presented and the two phenomenological models used to extract the nuclear parameters from the experimental data are fully discussed and compared. The electron scattering facility is described, emphasising the main experimental features and limitations. The inelastic scattering study of 26Mg is described in detail and a brief outline of the programs used to extract the form factors for the various levels from the raw data is also given. Transitions corresponding to 30 excited states of 26Mg were observed and the reduced transition probabilities and transition radii are deduced for 29 of these levels. Comparisons are made with the results obtained from other experimental studies, mainly fron Deppler Shift Attenuation. Discrepancies between the electron scattering and D. S. A. measurements are found to exist and are fully discussed. The predictions of various nuclear models are compared to the present experimental results. It is found that the C2, E2 and Ml transitions can be interpreted by various single particle transitions within the framework of the Independent Particle Shell Model.
