Investiagtion of Doppler effects in the n+Al and n+Li reactions at En+14.9 MeV

The shape of Doppler broadened γ-lines in n+27Al and n+7Li reactions at En=14.9 MeV is studied. In case of (n,pnγ), (n,pγ) and (n,αγ) channels on 27Al target predominance of a statistic mechanism of light particle emittance from the compound system is ascertained. The analysis of 7Li 0.478 MeV γ-line shape allows one to obtain data on angular distributions of inelastically scattered neutrons in (n,n'γ) reaction, and analysis of 26Mg(2+->0+) 1.8087 MeV γ-line shape - to solve the reverse problem of the method of γray energy Doppler shift attenuation
