摘要：

By applying the method of Hyland, Rowlands, and Cummings to pair-correlation functions obtained from new high-accuracy neutron-diffraction measurements, the condensate fraction, n0, in superfluid He4 has been determined for seven temperatures in the range 1.00<~T<~2.15 K. The results are very well described by the relation n0(T)=n0(0)[1-(TT)], with n0(0)=0.1330.012 and =6.21.6. © 1979 The American Physical Society.
