Numerical analytic approach to processing data from differential measurements on perturbed angular correlations

A numerical analytical approach to solving the problem of processing data from differential measurements on time-dependent perturbed angular correlations along the direction is described in this work. The method is applicable to perturbations that appear in the electric quadrupole interaction of the emitting nucleus with the external field. For the most frequently met spin case of an intermediate state I=5/2 (in the isotopes 181Ta and 111Cd, for example) in a closed form are given the corresponding formulae and the essential details for the realization of the method in a programme KATPAC for a small computer such as M-6000
