Electroproduction of medium- and heavy-mass hypernuclei

Abstract

The DWIA formalism for computing the cross sections in electroproduction of hypernuclei used before for lighter (p-shell and sd-shell) systems is utilized in studying electroproduction on heavier targets such as ${}^{52}$Cr, and ${}^{208}$Pb. First, the effects from kaon distortion and kinematics are re-examined and then results for the heavy targets are discussed in view of various forms of the $\hat{I}›$N effective interaction, the elementary amplitude, and kinematics. Apparent sensitivity of the hypernucleus excitation spectra to various forms of the $\hat{I}›$N effective interaction is shown. Predictions of the excitation spectrum in electroproduction of ${}_{\hat{I}›}^{208}$Tl are also given in kinematics of the experiment E12-20-013 in preparation at Jefferson Lab.

In the version v2, sections III and IV and Summary were revised, Fig.1 was omitted and new references added; more details on the formalism can be found in Phys. Rev. C 106, 044609 (2022) and ibid. 108, 024615 (2023)
