4 Results for As II

The computed oscillator strengths for transitions from the ground state of As II are presented in Table 4. There is no experimental data available for any of the transitions considered, but there is some theoretical data available. For the $\rm 4p-5s$ transition, the present value, 0.3547, is in good agreement with the theoretical value 0.32 ([Cardelli et al. 1993]), and is comparable to the theoretical values 0.292 ([Warner & Kirkpatrick 1969]), 0.26 ([Bieron et al. 1991]), and 0.23 ([Brage & Leckrone 1995]). For the $\rm 4p-4d$(³D $^\circ _{1}$) transition, the present value, 1.5497, is in good agreement with the theoretical value 1.4 ([Brage & Leckrone 1995]). There appears to be no data available for the higher transitions.
