The method of superfluid velocity measurement in He3-B
Zhao Zuyu, Adenwalla S., Ketterson J. B., Brusov P. N., Sarma B.K.
A doublet splitting of the squashing mode in He3 — B, which has been observed recently, is connected with the existence of superflow. We estimate the value of this effect on the basis of the Brusov-Nasten'ka-Kleinert theory. The possibility of using the collective mode splitting as a measure of superfluid velocity is discussed.
