The H dibaryon, a single, maximally symmetric bag containing two up, two down, and two strange quarks, has long been sought after in a variety of experiments. Its creation has been attempted with K{sup -}'s or protons as projectiles and most recently in relativistic heavy ion induced reactions. We concentrate on the latter, but our conclusions are more generally applicable. The two baryons coalescing to form the single dibaryon, likely {lambda}{lambda} in the case of heavy ions, must penetrate the short range repulsive barrier which is expected to exist between them. We find that this barrier can profoundly affect the probability of producing the H state, should it actually exist. (c) 1999 The American Physical Society.
