In this paper, by means of the extended average level (MODF-EAL) model of relativistio multiconfiguration Dirac-Fock code, we have calculated the fine-structure energy levels of 2s22p5,2s2p62,s22p43s,2s2 2p43p configuration and some transition wavelengths of 3s-3p configuration from F-Like ions of 41≤z≤48 which may be the candidates of lasing medium. The calculated values are first predicted except the two lowest levels.
