Measurement of the RLT, RL, and RT response functions for the 4He(e,e'p)3H reaction at large missing momentum.

Abstract

The $^{4}\mathrm{He}$(e,e'p${)}^{3}$H reaction has been measured at a missing momentum of 265 MeV/c. Data were taken to determine the ${\mathit{R}}_{\mathit{L}}$, ${\mathit{R}}_{\mathit{T}}$, and ${\mathit{R}}_{\mathit{L}\mathit{T}}$ response functions. The extracted response functions show substantial differences from a microscopic calculation that includes the plane wave impulse approximation, final state interactions, and meson exchange currents, but agree much better with a calculation that includes orthogonality corrections, short range correlations, and final state interactions.
