ISOELECTRONIC COMPARISON OF THE AL-LIKE 3S(2)3P(2)P-3S3P(24)P TRANSITIONS IN THE IONS P-III-MO-XXX

New observations of the 3s(2)3p P-2-3s3p(2) P-4 intercombination trans itions in Al-like ions have been made for Cl V from spark spectra reco rded at Lund and for Kr XXIV and Mo XXX from spectra obtained at the J ET tokamak. The new results have been combined with other identificati ons of these transitions along the sequence and empirically systematiz ed and compared with theoretical calculations. A set of smoothed and i nterpolated values for the excitation energies of the 3s3p(2) P-4 leve ls in P III-Mo XXX is presented.
