Abstract

We used the technique of the Bayes formula to estimate the relative error in the number of spectator nucleons using the information on the energy recorded by the calorimeter in the event of collision of relativistic nuclei. The minimum possible relative error in estimating the number of spectator nucleons in an event is obtained for an arbitrary general form of spectator distribution.
