Abstract
The two-fragment electrodisintegration of 4He into proton and triton is calculated in Plane Wave Impulse Approximation (PWIA). The three- and four-nucleon wave functions involved are obtained by solving the Alt-Grassberger-Sandhas (AGS) integral equations, with the Malfliet-Tjon potential as the underlying NN-interaction. Our results are in remarkable agreement with the experimental data and, in contrast to alternative approaches, do not exhibit any dip in the five-fold differential cross section at a missing momentum of ~ 450 MeV/c.
