A model containing the three fine-structure levels of the [2s 2][2p 5] and [2s2p 6] configurations has been adopted for Al V. Experimental energy levels come from the NIST database (Martin et al. 1995).
Due to the neglect of this ion in the literature, theoretical energy levels, radiative and collisional transition probabilities have been interpolated using all the other isoelectronic ions already inserted in the old version of the CHIANTI database. The program mentioned in Sect. 5.3 has been used.
