Capture cross sections and gamma-ray spectra for the neutron-induced reactions with mTa and 197Au have been calculated using the level density parameters derived from a new low-lying level fitting method in which the constant temperature partial level density formula and the spin-selected level cumulation were used. The gamma-ray profile functions, of the Brink-Axel type with an anomalous bump, were employed for both nuclei. The capture cross sections, spectra, and gamma-ray strength functions obtained in the present calculation agree well with the experimental ones.
