The ionization loss spectra of high-energy negatively charged particles which move in the planar channeling mode in a silicon crystal are studied with the use of numerical simulation. The case when the crystal thickness is on the order of the dechanneling length is considered. It is shown that in this case the shape of the spectrum noticeably depends on
. The evolution of various characteristic parameters of the spectrum with the change of
is investigated. A method of the experimental determination of
on the basis of the measurement of the ionization loss spectrum is proposed.
