| Excitation Autoionziation rate coefficients of Molybdenum ions are compared with those of Fournier et al. [ Phys. Rev.A. 54 3870 (1996) ]. For most cases compared, FLYCHK values are in agreement with the published values within a factor of two or better except for Mo32+ ions where the difference is a factor of 5. For this comparison, the two-electron collisional-excitation factor is set at 0.005. This factor may be too large for the L-shell ions such as Mo32+ (F-like ion). We plan to investigate this enhancement factor to reproduce Excitation Autoionization rate coefficients of more sophisticated calculations. |

| Dielectronic Recombination rate coefficients of Molybdenum ions are compared with those of Fournier et al. [Phys. Rev.A. 54 3870 (1996) ]. For most cases compared, FLYCHK values are in agreement witih the published values within a factor of two or better except for the low temperature cases where Δn=0 contributions of M-shell ions are dominant. However, ions such as Mo24+ or Mo25+ ions have very low population fractions in those temperatures and hence the discrepancies of these ions at low temperatures will barely make a difference in charge state distributions. Neverthless, the effect of no Δn=0 contribution in FLYCHK calculations should be estimated and one must find a way to include in the code. |

| Charge state distributions of Molebdenum ions are computed as a function of temperature in order to estimate the effect of uncertainties of Dielectron Recombination rate coefficients on the charge state distributions. The Mo24+ or Mo25+ ions have very low population fractions in low temperatures where the discrepancies between FLYCHK and Fournier results are the greatest. |  |
