Abstract:

Freeze out of particles across three dimensional space-time hypersurface is discussed in a simple kinetic model. The final momentum distribution of emitted particles, for freeze out surfaces with space-like normal, shows a non-exponential transverse momentum spectrum. The slope parameter of the

p_t

distribution increases with increasing

p_t

, in agreement with recently measured SPS pion and

h^-

spectra.
