Electroproduction of kaons and light hypernuclei

摘要: A detailed investigation of the basic hyperon-nucleon interactions in nuclei is one aims Experiment 91-016, approved with high priority at CEBAF, to study electroproduction kaons on targets deuterium, {sup 3}He, and 4}He. Inasmuch as both electron K{sup +} are particles that interact relatively weakly nucleons, light hypernuclei provides a low-distortion method for investigating fundamental between {Alpha}`s, {Epsilon}`s few-body systems. In particular, (e,e`K{sup +}) reactions cryogenic D, 4}He will be studied incident energies near 3 GeV coincident detection emergent e HMS SOS magnetic spectrometers Hall C.
