Abstract: The Rayleigh-Ritz variational method is used with a multi-configuration-interraction wave function on the bound state 1s²2s²¹S,and the excited states 1s²2s²p¹P^o,1s²2s2p ³P^o,1s²2p^{2 3}P for the berylliumlike Ne⁶⁺. A restricted varia-tional method is used to obtain an additional nonrelativistic energy for these states. The relativistic corrections and mass polarization are taken into consideration in the calculation of total energy. The wavelengths,oscillator strengths and radiation rates are also calculated.

Key words: berylliumlike ion, excited state, oscillator strength
