Response Functions with Target and Recoil Polarization

36 response functions, for definition see e.g.
D. Drechsel and L. Tiator, J. Phys. G 18 (1992) 449-497 or
G. Knoechlein, D. Drechsel, L. Tiator, Z. Phys. A 352 (1995) 327-343
(see further details on response functions)

Note!  The target polarization is fixed to the {x,y,z} frame in the reaction plane,
the recoil polarization frame can be chosen
(see further details on coordinate frames)
