For the lowest 50 levels, the following radiative data have been calculated using the Multi-Configuration Dirac–Fock (MCDF) approximation: transition wavelength, transition rates, oscillator strength, line strength, and radiative rates like the electric dipole (E1) and electric quadrupole (E2) transitions of the highly ionized Ne-like Se⁺²⁴ ion (Se XXV) and magnetic dipole (M1) and magnetic quadrupole (M2) transitions. GRASP and FAC were used to calculate the results. For Se XXV, our measured excitation energies, wavelengths, oscillator strengths, and line strengths all correspond well with the existing data, including the NIST data. We have also calculated Einstein coefficients for the spontaneous emission, stimulated emission, transition dipole moment, emission and absorption oscillator strength, and E1 transitions for Se XXV. Lifetimes for the lower levels of Se XXV have also been computed. Our computed atomic and radiative data of Ne-like Se should be useful for the identification and evaluation of spectral lines from various fusion plasmas, solar plasma modeling, and astrophysical investigations.
