Abstract

Negative ion mobility in rotating 3He-B at magnetic fields H = 0.1 T has been measured along the common direction of H and the rotation axis Jz. When Sa > 0, we observed an increase of mobility, which originates from a reorientation of the anisotropic energy gap. The increase can be understood quantitatively only if soft vortex cores, predicted by Sonin, are assumed. Their size was found to be on the order of the magnetic Healing length EH.
