  General features of spontaneous baryogenesis are studied. The relation
between the time derivative of the (pseudo)goldstone field and the baryonic
chemical potential is revisited. It is shown that this relation essentially
depends upon the representation chosen for the fermionic fields with non-zero
baryonic number (quarks). The calculations of the cosmological baryon asymmetry
are based on the kinetic equation generalized to the case of non-stationary
background. The effects of the finite interval of the integration over time are
also included into consideration. All these effects combined lead to a
noticeable deviation of the magnitude of the baryon asymmetry from the
canonical results.
