Singularity of the diameter of the coexistence curve of ethane
Bulavin L.A., Shimanskii Yu.l.
To determine the temperature dependence of the diameter of the coexistence curve of ethane, we obtained data on the location of the phase boundary at 10~3 <|r|< 5X 10~2, using the method of slow-neutron transmission. The obtained values Ι-α-β = 0.57+0.04 and β = 0.337 + 0.006 are in agreement with the gauge theory: pd ~|r|°91±005.
