Nature of problem:It is well known that comparison of experimental reduced transition probabilities with their model-dependent predictions is of great importance for studying nuclear structure. Namely, the influence of the coriolis particle-rotational coupling on electromagnetic transitions between excited states in odd-A deformed nuclei has been the subject of interest in many papers and has been reliably demonstrated. The analogous situation in odd-odd nuclei has also been established. The program makes it possible to calculate the E1, E2 and M1 reduced transition probabilities in odd-odd deformed nuclei. The mixed wave functions used result from a least-square fit of energy levels (taking the Coriolis effect into account) to the experimental ones, performed with the modified ODDODDCORI subprogram. | ||

Solution method:The calculation of the reduced electromagnetic probabilities can be subdivided into two stages. In the first stage, the total Hamiltonian (with Coriolis coupling term included) is diagonalised and eigenvalues and eigenvectors are found. In the second, the coupling amplitudes obtained in the first stage are used for the calculation of the electro- magnetic operator matrix elements, performed with the present program. | ||

Restrictions:The current version is dimensioned for 40 transitions. |
