Abstract
The form factors of the weak currents, which appear in the semileptonic
decays of the heavy pseudoscalar mesons are calculated within the quark
confinement model by taking into account, for the first time, the
structure of heavy-meson vertex and the finite quark mass contribution
in the heavy-quark propagators. The results are in quite good agreement
with the experimental data.
