Abstract
The relativistic distorted-wave impulse approximation (RDWIA) is used to describe the 4He(e; e′p)³H process. The 4He ground state is determined within a relativistic mean field bound state fit to elastic electron scattering data. The nucleons are described by solutions of the Dirac equation with scalar and vector (S–V) potentials. The wave function of the outgoing proton is obtained by solving the Dirac equation with a S–V optical potential fitted to elastic proton scattering data on the residual nucleus. Experimental cross sections for the 3-body breakup 4He(e; e′p)³H up to pmiss = 0:632 GeV/c at xB = 1:24 and Q² = 2 (GeV/c)² are compared to the RDWIA calculations. [ABSTRACT FROM AUTHOR]
