Energy levels, wavelengths, transition rates and line strengths are reported for the 2s 2 2p 3 2s2p 4 transition array in Kr(XXX), Rb(XXXI) and Sr(XXXII). Wave functions were determined using the multiconguration Dirac Fock method with account for valence and core-valence correlation eects. The present results are presented and compared with experimental data and with values from other calculations. The calculated values including corevalence correlation are in good agreement with other available theoretical and experimental values, and therefore can be used for the further astrophysical investigations.
