  The longitudinal structure function of the d(e,e'p) exclusive cross section
is calculated with the Lorentz integral transform method. In this approach
final state interaction is fully taken into account, but without using a final
state wave function. Cross sections are obtained via the inversion of the
transform. It is shown that the inversion results are very stable. The
comparison to a conventional calculation with an explicit np final state wave
function shows that the obtained results are also very precise. Thus the method
opens up the possibility to obtain exclusive cross sections for reactions with
more than two particles, where it is generally very difficult to calculate the
exact final state wave function.
