Abstract

The first experiments on rotating 3HeA1 have been done using pulsed zero sound transmission techniques at several pressures in magnetic fields up to 1 T. Preliminary analysis of our data by a geometrical acoustics method suggests that the vortex cores in 3HeA1 are larger than in 3HeA2. This result is based on the strong and highly non-linear rotation dependence of sound attenuation in 3HeAl. Conclusions about the type of vortices in 3HeA1 cannot be made at present owing to lack of theory.
