Abstract

The system C

S_{2}

+ C

H_{3}

N

O_{2}

shows

β = 0.315 \pm 0.004

over

10^{- 6} < ε = \frac{| T - T_{c} |}{T_{c}} < 2 \times 10^{- 1}

with no indication of a classical value ½ even far away from

T_{c}

. The diameter shows a curvature and is of the form

ϕ_{c} + b ε + f ε^{\frac{7}{8}} \exp (- g ε^{h})

.
