INTERACTIONS AT LARGE DISTANCES
AND SPIN EFFECTS IN NUCLEON-NUCLEON AND
NUCLEON-NUCLEI SCATTERING
Cudell J.-R., Predazzi E., Selyugin O. V.
The momentum-transfer dependence of the slopes of the
spin-non-flip and spin-flip amplitudes is analyzed. It is shown that
the long tail of the hadronic potential in impact parameter space leads
for hadron-hadron interactions to a larger
value of the slope for the reduced spin-flip amplitude than for the
spin-non-flip amplitude. It is shown that the preliminary measurement
of AN obtained by the E950 Collaboration confirms
such a behaviour of the hadron spin-flip amplitude.
