Abstract: Almost all the data used in this work is based on the plates taken on a 3m Normal Incidence Vacuum Spectrograph at the Physics Department, Saint Francis Xavier University, Antigonish, Nova Scotia, Canada. Four Configurations 5s27p, 5s28p, 5s29p and 5s25f of odd parity and 13 levels of j=1/2 and 3/2 of even parity of 5p25d are investigated in this paper.5s29s is also newly established level in even parity. The Hartree Fock calculations with relativistic corrections and parametric levels fitting calculations were carried out to interpret the spectrum satisfactorily
