Abstract In this code, the energy spectra of nuclei and the first- and second-order reduced nuclear matrix elements for coupled-channel calculations are computed. To describe the structure of the target nucleus, the Davydov-Chaban model, including quadrupole and hexadecapole modes, was used. Title of program: DAFICHA Catalogue Id: ACLQ_v1_0 Nature of problem Reduced matrix elements needed for coupled channel calculation in the frame of the Davydov-Chaban model are computed. Interacting potential is expanded in power of deformation paramemeters up to the second order terms, including the quadrupole and hexadecapole modes. The nuclear spectrum of Davydov-Chaban model is also computed. A search procedure of model parameters on the basis of the experimental spectra is included.
