For investigating the ⁴Σ^-→ ⁴Σ^- transition in the FO radical to which an observed 268 nm ASE line has been attributed,the potential energy curves of the four lowest-lying ⁴A₂ states of FO have been calculated using the MRSDCI method.The results indicate that the first ⁴Σ^- (l⁴A₂) and the upper ⁴Σ^-(4⁴A₂) states are weakly bound and bound states respectively,and the 2⁴A₂ and 3⁴A₂ states are both repulsive states which are not relevant to the emission.The predicted Te value for the ⁴Σ^-→ ⁴Σ^- transition is 4.62 eV,which is in excellent agreement with the photon energy value (4.63 eV) of the ASE line.The procedure of our MRSDCI calculations for excited states is described in detail,and the previous calculation results for these states are discussed.
