Formulation of a model for description of nonadiabatic effects in deformed nuclei at moderately fast rotation

A model is constructed for measuring collective parameters of even-even deformed nuclei in rotation. Approaches are formulated based on certain suppositions about basic non-adiabatic effects in the range of not very high spins which allow constructing a realizable system of equations. On this basis there were obtained experessions for the state energy of the main rotational band and for matrix elements of physical operators acting between these states and defining the principal collective parameters of the nucleus. The values of interest are described in terms of the density matrix
