The observed 4f3 energy levels of La isoelectronic sequence ions Pr2+ and Nd3+ were analyzed using a standard f-shell free-ion Hamiltonian. The root mean square (rms) deviation of 13.54 cm-1, 6.17 cm-1 between calculated and observed energies were obtained from the fit of 16 free-ion parameters to 38 levels for Pr2+, and to the complete set of 41 levels for Nd3+, respectively. Then, the fitted values of free-ion parameters were used to compute wavelengths, oscillator strengths, and transition rates for the forbidden magnetic dipole and electric quadrupole transitions between the 4f3 levels in Pr2+ and Nd3+ La-like ions. Detailed comparisons with other available theoretical data are also reported and discussed in this work.

Keywords:energy levels; La-like ions Pr2+ and Nd3+; Magnetic dipole transitions
