By means of extended average level model of relativistic multi-configuration Dirac-Fosk code, we have calculated 33 fine-structuie energy levels of 2s22p5, 2s2p6, 2s22p3s, 2s22p43p configuration and 54 transition wavelengths of 3s-3p for IP-like ions of 33≤Z≤40, which may be the candidates for lasing action. Greater part of the calculated values are firstly predicted.
