Mossbauer measurementswere made on disordered Fel Al"alloys over the range 0&x &0.04 in order to determine the critical exponent P. It was found, in agreement with theoretical predictions, that P remains unchanged with the addition of disorder. With the use of analysis that contains correction to scaling terms, a mean value of P =0.366(2) was found for five measurements. This is in excellent agreement with the renormalizationgroup prediction of P =0.365{1). A model was developed to help interpret critical behavior . in the presence of a small distribution of critical temperatures observed in the alloy measurements.
