Abstract:

The Rydberg Series and Radiative transitions in Beryllium ions have been investigated using the single-electron approximation i.e. Weakest bound electron potential model theory (WBEPMT) and quantum defect theory. The Martin expression was applied to evaluate energies and quantum defects of Rydberg levels of Be III up to n = 50. The lifetime of 157 levels have been calculated using transition probabilities of the radiative transitions. The necessary data was taken from NIST database. The radii of Rydberg levels have also been calculated.
