[en] This investigation treats the angular dependence of the intensity and of the circular polarization of gamma-radiation, that is emitted after capture of polarized neutrons by polarized and unpolarized targets. Interference effects between the (n,γ)-reaction amplitudes with different channel spin are discussed and angular distribution coefficients are calculated in case mixing of dipole and quadrupole radiation occurs. It is indicated how the influence of p-wave capture may be taken into account. The nuclear orientation experiments on aluminium yield the values of the angular distribution coefficients of primary and secondary gamma-ray transitions and by a chi²-analysis five spin values are assigned uniquely and several α-values are determined. The nuclear orientation experiments on manganese lead to α-values and unique spin assigments for thirteen nuclear states in ⁵⁶Mn. (Auth.)
