摘要：

Oscillator strengths and transition probabilities are calculated for the np3-np2(n + 1)s transition array in As I, Sb I and Bi I spectra. Lifetimes of the levels belonging to the np2(n + 1)s configuration are derived. Relativistic self-consistent-field spin orbitals employed in calculations are generated using the multiconfiguration Dirac-Fock computer code. Modification of the standard CI method proposed recently is also investigated. The effect of the configuration interaction on calculated oscillator strengths computed in Babushkin and Coulomb gauges is discussed. Results obtained are compared with other theoretical calculations as well as with available experimental data.
