摘要：

A fast hadron formed inside a nucleus collides with other nucleons on its passage out and may be absorbed. We present here an analytically solvable model: a positronium traversing N randomly oriented electric condensers, which may be related to the passage of a newly formed cc pair through the chromo-electric fields of the nucleons comprising the nucleus. The resulting absorption depends in a non-linear way on the initial size of the hadron. © 1990.
