We present results for response functions and asymmetries in the nuclear reactions 3 7 Ar(e,e n) 3 6 Ar and 3 7 K(e, e p) 3 6 Ar at quasifree kinematics. We compare PWIA results obtained using deformed HF wave functions with PWIA and DWIA results obtained assuming a spherical mean field. We show that the complex structure of the deformed orbitals can be probed by coincidence measurements with polarized beam and targets.
