Measurements of the relative changes 
of the electron
capture rate is a direct experimental way to determine the changes
of electron density on the nucleus 
, which are
necessary for the determination of the Mössbauer isomer shift calibration
constants. In this paper we present our results obtained using various
chemical compounds with 
isotope. Fitting the results to
the theoretical model, we find the parameters, and using a genetic algorithm
we solve the so-called "ill-posed"problem. The calculated
values compared with 
are (
for 
, (
for
, (
for CsI.
