1. Decay Modes of a (θ+θ¯) System
2. From a practical point of view it may be desirable, in order to enrich the sample with events, to surround the hydrogen target with anticoincidence counters. To observe Kz decays high precision is needed, such as is already obtainable with streamer chambers. To observe KL decays, very large volume detectors would be needed.
