The "incoherent droplet model" is used to explain recent experiments on the fragmentation of 16O during high energy collision with a Be target. In the 16O rest frame the fragments have a universal iso tropic Gaussian momentum distribution, independent to the masses of the fragments. The half-width of the Gaussian is 〈p〉 (A3n), where, A is the mass number of the nucleus, n is the total number of fragments, and 〈p2〉 is the mean square momentum of individual nucleons in the fragmenting nucleus.
