Spectroscopic study of {lambda} hypernuclei by the (e,e'K{sup +}) reaction

Abstract

The hypernuclear spectroscopy via the (e,e'K{sup +}) reaction has been carried out for the first time. The high quality electron beam at Jefferson Lab made it possible to measure {lambda} hypernuclear spectra with energy resolution better than 1 MeV (FWHM). The present experiment was designed to make full use of virtual photon flux which peaks at very forward angles by detecting scattered electrons at 0 degrees. The {sub {lambda}}{sup 12}B mass spectrum was measured in the {sup 12}C(e,e'K{sup +}) {sub {lambda}}{sup 12}B reaction with 0.9 MeV (FWHM) energy resolution. The binding energy and cross section of the {sub {lambda}}{sup 12}B ground state doublet were obtained and discussed in this article. The present study proved the effectiveness of the (e,e'K{sup +}) reaction in the future {lambda} hypernuclear spectroscopy. (author)
