Electroproduction of medium- and heavy-mass hypernuclei

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 $Λ$N effective interaction, the elementary amplitude, and kinematics. Apparent sensitivity of the hypernucleus excitation spectra to various forms of the $Λ$N effective interaction is shown. Predictions of the excitation spectrum in electroproduction of $^{208}_{~~Λ}$Tl are also given in kinematics of the experiment E12-20-013 in preparation at Jefferson Lab.
