摘要：

We have constructed and used a low energy, wide energy band, large solid angle K+ detector in LEAR experiment PS177. In this application, the detector is used to search for hypernuclear effects in association with fission induced in a uranium target by antiproton annihilation at rest. We identify K+ in the momentum range 250-750 MeV/c in a solid angle of 16% of 4π sr. The yield of K+ is in good agreement with predictions based on a Monte Carlo simulation and previous measurements of inclusive antiproton annihilation in uranium. © 1990.
