Abstract
Spike production is studied in pp and pi(+)p/K(+)p collisions in the b eam-momentum range of 205-360 GeV/c. The pseudorapidity distribution o f spike centers exhibits two narrow peaks in pp interactions, while ha ving one wide bump in pi p and Kp interactions, The position of the pe aks is consistent with the expectation from a model of coherent gluon radiation at finite length, The interference between the quark color a mplitudes obtained within this model causes two off-center peaks in pp data, but only one central peak in pi p and Kp data.
