Fine structure calculations of the energy levels, the wavelengths, the oscillator strengths, log gf and the transition probabilities for transitions among the terms belonging to 1s2 2s2 2p6 3s2 3p6 3d10ns, n=5-10, 1s2 2s2 2p6 3s2 3p6 3d10np, n=4-10 , 1s2 2s2 2p6 3s2 3p6 3d10nd, n=4-10 and1s2 2s2 2p6 3s2 3p6 3d10nf, n=4-10 configurations of As (III) have been calculated using configurations interaction Cowan atomic structure code. Our calculated values for the above mentioned quantities have been compared with the corresponding experimental data and other theoretical calculations where a satisfactory agreement has been obtained. We also report on some unpublished corresponding values for As like gallium.
