THE BREATHING MODES OF THE B = 2 SKYRMION AND THE SPIN-ORBIT INTERACTION

The coupling of the breathing and rotational modes of the skyrmion-skyrmion system leads to a nucleon-nucleon spin-orbit interaction of short range, as well as to spin-orbit potentials for the transitions NN → N(1440)N, NN → NN(1440) and NN → N(1440)N(1440). The longest range behaviour of these spin-orbit potentials is calculated in closed form.
