摘要/Abstract

摘要： Variational calculations are carried out with a multiconfiguration-interaction wavefunction on the 1s²2p2p ¹D^e and 1s²2p3p ³P^e states to obtain the energies including the mass polarization and relativistic corrections for the beryllium isoelectronic sequence (Z=4--10). The oscillator strengths,transition rates and wavelengths are also calculated. Our results are compared with other theoretical and experimental data in the literatures. The fine structure and hyperfine structure of 1s²2p3p³P^e state are also explored.
