A separation of the longitudinal and transverse C-12(e,e'p) cross sections
in the quasifree region has been performed in parallel kinematics at Q(2) o
f 0.64 and 1.8 GeV2 for initial proton momentum <80 MeV. The separated tran
sverse and longitudinal spectral functions at Q(2) = 0.64 GeV2 show signifi
cant differences for missing energy between 25 and 60 MeV indicating a brea
kdown in the single nucleon knockout picture. The transverse spectral funct
ions exhibit definite momentum transfer dependence.
