Woelfle, P

It is shown that the anomalous zero-sound attenuation at the transition''A'' observed recently in liquid /sup 3/He at about 2.7 mK can be understood by postulating pairing a state of odd relative angular momentum. The attenuations is found to depend strongly on the angular variation and orientation of the gap parameter, providing information on the precise nature of the pairing. It is concluded that (1) Balean-Werthamer p-wave pairing can be ruled out, and (2) Anderson-Morel p-wave pairing is possible. (auth)
