NuclearγRays Associated with Stopped Kaons

Abstract

We have identified a large number of nuclear $\gamma$ rays associated with negative kaons stopped in Ni, Cu, Si, and Al. Prominent among these for both the Cu and the Ni targets are transitions that take place in even-even nuclei lighter than the target by up to about twelve nucleons. In both cases, the total intensity of all of the identified nuclear $\gamma$ rays amounts to about twice that of the strongest x ray.
