Transition wavelength and fine structure for the quartet states ofBe+

Twenty-four quartet states of ${\mathrm{Be}}^{+}$ are calculated using configuration-interaction wave functions. Relativistic and mass polarization corrections are included. The relativistic corrections considered are mass correction to the kinetic energy, Darwin term, and retardation effect. The fine structure is calculated using spin-orbit, spin-other-orbit, and spin-spin operators. The transition wavelengths calculated in this work improve the agreement between theory and experiment in most cases. The lifetimes computed in the present work generally agree with those of the experiment. However, we also point out that the observed line at 3530 Å may have been misidentified in the literature.
