摘要：

A method is proposed to probe the size of dense k nuclear clusters by observing the momentum correlation in their 3-body decay products, such as [pppK(-)]((T=1)) -> Lambda + p + p and [ppnK(-)]((T=0)) -> Lambda + p + n. The calculated momentum correlation pattern expressed in a Dalitz 14 plane shows characteristic features, reflecting the size/density and the angular momentum of the parent k cluster.
