Abstract：
The increase of the width of the momentum distribution of He fragments with decreasing He-multiplicity in relativistic ¹⁶O fragmentation at 2GeV/N to 200GeV/N is analyzed.The result shows that with decreasing He-multiplicity the surface-excitation energy of the projectile-spectator increases,which is the reason of the increase of the width of the momentum distribution.Although the incident energy changes the projectile-spectator obtains the same excitation energy under the same geometric conditions.This gives the limiting fragmentation behavior of the He-multiplicity distribution.
