SINGLE-FOLDING MODEL FOR THE SPIN-ORBIT POTENTIAL BETWEEN F-19 AND SI-28

A general expression for the spin-orbit potential between two heavy ions is derived using the single-folding method. This expression is applied to the calculation of the spin-orbit potential between F19 and Si28, using single-particle as well as cluster model wave functions for F19. In the cluster model, the magnitude of the F19 + Si28 spin-orbit potential at the strong absorption radius is enhanced by a factor of 50 over the singleparticle model estimate.
