摘要：

A1-symmetry internal modes and B2-symmetry soft-mode were studied in KH2(P1-x)Asx)O4 crystals for x=0.14 and 0.2 as a function of temperature between 298K and 18K. The two-mode behaviour A1-mode Raman bands and the one-mode behaviour B2-mode Raman bands are both informative of the site symmetry relaxations and phase transition in the mixed crystal between KDP and KDA.
