Description
Energy dependence of the total cross sections σ${_{\rm{R}}}$(E) for reactions ${}^{10,11,12}$Be + ${}^{28}$Si, ${}^{59}$Co, ${}^{181}$Ta are presented. The 4π-methods of σ${_{\rm{R}}}$ measurements are based on registration of prompt γ-quanta and neutrons using a 12-module 4π-spectrometer [1]. The results of the two methods for calculating the total reaction cross sections are presented.
The values of σ${_{\rm{R}}}$ were calculated taking into account:
- the mean detection efficiency <ε> of the 4π-spectrometer, which does not depend on γ-multiplicity M${_{{\gamma}}}$ [2];
- the distribution of the numbers of triggered detectors during registration of the cascades of particles at a fixed value of multiplicity M${_{{\gamma}}}$.
Measurement of the detection efficiency ε(M${_{{\gamma}}}$) for various values of γ-multiplicity M${_{{\gamma}}}$ was carried out using the method described in [3].
