The algorithm of Rayleigh intensity correlation is employed for the elucidation of relaxa-tion time constants of the aqueous NH_4H_2PO_4 solution with various concentrations.The resultshows that there is a discontinuous(abrupt)increases in the relaxation time constant as the super-saturation state is reached.This quantity,the relaxation time constant,therefore,can be an orderparameter.Also discussed is the dependence of the relaxation time constant on the aggregationnumber n in(H_2PO_4~-)_n.This dependence is complicated and may be crucial in understanding theaggregation process in the supersaturation state.

The result shows that there is a discontinuous (abrupt) increases in the relaxation time constant as the super-saturation state is reached . This quantity, the relaxation time constant, therefore, can be an order parameter. Also discussed is the dependence of the relaxation time constant on the aggregation number NUn (H_2PO_4 ~ -) _ n.This dependence is complicated and may be crucial in understanding the augmentation process in the supersaturation state.
