This paper presents new results on the maximum gap (D
max) in the pseudorapidity distribution
of charged particles in individual events in 24Mg-AgBr, 16O-AgBr
and 32S-AgBr interaction in the energy range 4.5 - 200 AGeV.
The location of the Dmax
in an event and the experimental Dmax
distribution at all energies has been
studied in details. It has been observed that Gaussian distribution can describe
the experimental data satisfactorily over the entire energy range.
