Available in PDF, EPUB and Kindle. Book excerpt: Jefferson Laboratory experiment E89-009 used the reaction (e,e' K+ ) to produce $12top{Λ}$B hypernuclei from a carbon target. The scattered electrons were tagged at 0° to take advantage of the increased virtual photon flux at forward angles, and the electroproduced kaons were also detected at small angles, 3̃°, to minimize the momentum transfer. To do this, a splitter magnet was used to bend the scattered electrons into an Enge split-pole spectrometer and the kaons into a short orbit spectrometer. In addition to increasing the production rate, tagging the scattered electrons at 0 degrees minimizes the optical aberrations on the focal plane of the Enge split-pole spectrometer. In this experiment, the spectroscopy of the $12top{Λ}$B hypernuclei was studied and excellent energy resolution was achieved, ̃918 keV. The differential cross section of the ground state doublet was also calculated.

Book excerpt: The first electroproduction experiment of a hypernucleus was undertaken at the Thomas Jefferson National Acceleration Facility. The (e, e'K+) reaction was used on a natC target resulting in the observation of the 12LB hypernucleus. The excitation spectrum is presented and discussed.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High energy CW electron beams at new accelerator facilities allow electromagnetic production and precision study of hypernuclear structure, and we report here on the first experiment demonstrating the usefulness of the (e, e'K+) reaction. This experiment is also the first to take advantage of the enhanced virtual photon flux available when electrons are scattered at approximately zero degrees. The observed resolution, ~900 keV, of the 12B(hypernuclear) spectrum is the best yet attained using magnetic spectrometers. The positions of the major excitations are in agreement with theoretical predictions and the previous binding energy measurements.

Available in PDF, EPUB and Kindle. Book excerpt: The first Lambda-hypernuclear spectroscopy study using an electron beam has been carried out at Jefferson Lab. The hypernuclear spectrometer system (HNSS) was used to measure spectra from the 12C (e, e'K+) 12Lambda B reaction with close to 1 MeV resolution, the best energy resolution obtained so far in hypernuclear spectroscopy with magnetic spectrometers. This paper describes the HNSS and preliminary results for the 12Lambda B system. A program of hypernuclear physics experiments is planned for the future with much higher yield and even better energy resolution.
