  The population of solitary compact objects in the Galaxy is very diffcult to
investigate. In this paper we analyze the possibility of using microlensing
searches to detect and to analyze the properties of the solitary black holes
and neutron stars. Evolution of single and binary stars is considered using the
StarTrack population synthesis code. We investigate the properties of the
Galactic population of compact objects numerically. We find that the compact
object lensing events are concentrated in a region with the radius of $\approx
5$ degrees around the Galactic center. The distribution of masses of the lenses
for the models we consider differs but only slightly from the underlying
massdistribution. The expected detection rates are of the order of a few per
year.
