Neutron resonance parameters of 55 Mn from Reich-Moore analysis of recent experimental neutron transmission and capture cross sections

the d-wave resonances were identified with a possible strength function of S2 = 1.0 x 10 -4 . The capture cross section calculated at 0.0253 eV is 13.27 b, and the capture resonance integral is 13.52 ± 0.30 b. In the energy range 15 to 120 keV, the average capture cross section is 12% lower than Lerigoleur value and 25% smaller than Macklin value. GELINA and ORELA experimental capture cross sections show a background cross section not described by the Reich-Moore resonance parameters. Part of this background could be due to a direct capture component and/or to the missing d-wave resonances. The uncertainty of 10% on the average capture cross section above 20 keV is mainly due to the inaccuracy in the calculation of the background components.
