Research output: Contribution to journalArticlepeer-review


Results of zero-sound attenuation measurements in He3-B, at frequencies up to 60 MHz and pressures between 0 and 20 bars, are reported. At frequencies of 30 MHz and above, a new attenuation feature is observed which bears the signature of a collective mode of the superfluid.
