    Notes: Abstract We calculate the energy gap for deformed nuclei using the gap equation which appears in the Migdal theory of finite Fermi systems with pair correlations. To obtain good agreement with experiment for nuclei with neutron excess, it is necessary to choose differently the forms of the density dependent residual interaction for the protons and neutrons because of the difference between their density distributions. The distributions we get are in good agreement with experiment as well as with other theoretical predictions. We also show which approximations are required to reduce the general gap equation to the special Migdal equation.

    Notes: Abstract A new approach is made to calculate the generalized single-particle density matrixp μv in even-even nuclei. It is shown that this quantity is included in the three particle response function, for which we derived a renormalized equation. Taking into account in a consequent way the effective particle-hole interaction we received a formula for the static moment of excited states and the transition probability between such states which is essentially different from the usual RPA theory.
