Many papers have been devoted recently to particle-rota-University of Belfast, N. Ireland (see application form in tional coupling (Coriolis effect) in odd deformed nuclei this issue) (e.g. refs. [1-41), when the experimental spectrum could be often explained by this coupling. Therefore, one can Computer: CDC 6500;Installation: Laboratory of Calcula-expect that the Coriolis coupling plays, as well, a signiuiting Techniques and Automation, Joint Institute for Nuclear cant role in odd-odd deformed nuclei for which a lot of Research, Dubna, USSR experimental data appeared lately (e.g. ref. [5]). The program makes it possible to extract pure intrinsic energy Operating system: NOS/BE 1 values from experimental data. This is important for testing the theoretical models for intrinsic structure of odd-odd Programming language used: FORTRAN nuclei. The program calculates the perturbed energy levels. It is written as a subroutine to be used with the MINUIT High speed storage required: 32100 words (MINUIT included) minimization program [6], Which makes a least-square fit to the experimental energy levels. Mixed amplitudes of the No. of bits in a word: 60 wave functions are obtainedfor the final fit. Oyerlay structure: none Method of solution In order to take the Coriolis coupling into account, the No. of magnetic tapes required: none matrix of the total Hamiltonian is constructed and diagonalized. The Jacobi diagona~ization method is used repeated-Other peripherals used: card reader, line printer ly in the search for eigen values and coupling and amplitudes for all spin values. Simultaneously, the adjustment of all the No. of cards In combined program and test deck: 1204 parameters is carried out until a least-square fit to the experimental energy levels is obtained.
