Multistage emission of $\gamma$-quanta in reactions of neutron capture by nuclei at medium energies

The possibility of describing a nonequilibrium gamma spectrum in the $(n,\gamma)$ reaction at $\varepsilon_n$ = 14.1 MeV using the quantum model of statistical multistage compound processes (SMCP) and statistical multistage direct processes (SMDP). It is shown that a consistent description of experimental data can be obtained for the $(n,\gamma)$ reactions at $\varepsilon_n$ = 14.1 MeV on $^{93}Nb$ and $^{133}Cs$ nuclei if contributions from lSDP, 2SDP, SMCP, and equilibrium gamma emission are taken into account.
