New experimental results for the optical collision process
are presented, which were obtained in a crossed-beam
experiment with differential detection. The oscillatory structure
in the differential cross-sections caused by Stueckelberg interferences
is investigated in detail for relative velocities between 450 and 1500 m/s
and for laser detunings 
from 80 to 
on the blue-wing side of the Na resonance lines.
The data are used to determine the potential of
the excited repulsive 
state of NaKr with an estimated accuracy
of 
(3 meV).
