Our proposed technique allows the function n(t) to be reconstructed
from the
histogram in low transverse magnetic field
without presupposing a particular theoretical form, i.e. with no
parametrization. The technique is based on solving the integral equation of
the first kind for the muon polarization function using the maximum
likelihood method. The obtained results are of fundamental importance for
the analysis of the charge kinetics in superfluid helium.
