Abstract

The ⁴⁰Ca(¹³C, ¹⁴N)³⁹K reaction at 60 and 68 MeV has been investigated in the no-recoil approximation to the DWBA. Reorientation effects arising from the quadrupole moments of ¹⁴N and ³⁹K were found to be small. The use of spin-orbit components in the optical potentials was found to shift the phase of the angular distribution into agreement with experiment, while maintaining a fit to the elastic data. This was understood from a generalization of the Strutinsky model. For the ⁴⁰Ca(¹³C, ¹²C)⁴¹Ca reaction at 60 and 68 MeV a smaller shift in phase was obtained which was desirable, but the damping of the magnitude of the oscillations was disturbing.

Funding Information:
It therefore still seems worthwhile to pursue alternative explanations for the data and here we shall concentrate on spin-dependent effects. Firstly, we note that both "N and 39K possess sizeable quadrupole moments. The optical potential should therefore be deformed, which gives rise to non-spherical reorientation terms.
