Abstract

Abstract The flux-averaged cross-sections

for the reactions

, and

have been measured within the bremsstrahlung end-point energy

range of 35–94 MeV. The experiments were performed with the electron beam from the NSC KIPT linear accelerator LUE-40 with the use of the activation and off-line γ-ray spectrometric techniques. Theoretical calculation of the flux-average cross-sections

was conducted using the cross-section

values from the TALYS1.95 code, run with default options. It is shown that the experimental average cross-sections for the reactions

, and

are systematically higher than the theoretical estimates based on the TALYS1.95 code. The obtained

values supplement the data of different laboratories for the

and

reactions of

and

. For the reaction

, the values of

were measured for the first time.
