The "quadrupole plus pairing" collective model is constructed for the micro
scopic description of low-lying collective states of even-even transitional
nuclei. Inclusion of the model to the core-quasiparticle coupling model in
order to describe odd nuclei is realized. An approximation scheme suitable
for investigation of the quadrupole excitations is demonstrated. Exemplary
results of microscopic calculations for the Ru isotopes are shown. (C) 200
