In this letter we address the long-standing controversy which originated from
differences between the experimental and theoretical values of the scaling
exponent 
for the critical amplitude 
of the correlation length in polymer
solutions. Using small-angle neutron scattering we examine the dependence
of on polymer molecular weight in polystyrene-methylcyclohexane-
solutions. We find that the experimental values of 
in the
critical region of phase demixing as well as 
in the mean-field
domain around the Θ temperature agree with the predictions of scaling
theory
