Neutron inelastic scattering cross sections for molybdenum isotopes are calculated with the DWBA and the coupled-channels methods. Anomalous enhancement of the DWBA cross sections near the threshold energy appears when the adopted optical potential has a shallow imaginary part. Calculations with some simplified optical potentials indicate that the enhancement can be related with the p-wave strength, and it is found that the problem comes from the optical potential used.<BR>When an adopted optical potential to the DWBA calculation is physically reasonable, differences between the calculated cross sections with the DWBA and those with the coupled-channels theory are small. Experimental data of <SUP>92</SUP>Mo, <SUP>98</SUP>Mo and <SUP>100</SUP>Mo are well reproduced by the calculated cross sections with the DWBA and the Hauser-Feshbach-Moldauer statistical model, and it is concluded that the DWBA is an appropriate method to evaluate cross sections of inelastic scattering from the molybdenum isotopes.
