On the axial shadow form at large coumpound nucleus shift

Developed is a model, discribing the form of particle angular distributions, leaving the monocrystal in the crystallographic axes direction. The potential of particle interaction with the crystal was chosen as a sum of interaction potentials with neighbouring chains and that is why was of axial asymmetric form. The effect of the compound nuclei life time on the angular distribution form of nuclear reaction products is investigated within the frames of this model. It is obtained, that the form of angular distribution depends both on the shift value during life time of the compound nuclei and on the direction of the compound nuclei shift from lattice point in the plane perpendicular to the given crystallographic axis. It is shown, in particular, that for certain orientations and with essential shift values (normal constituent of average shift of the compound nuclei during its lifetime 0.1 n) of the compound nuclei the minimum in angular distribution of reaction particle-products can transfer into maximum. Alongside with it there are integral characteristics of angular distributions, which weakly depend on the orientation of the compound nuclei shift at high sensitivity to the shift value
