We study here the tilt angle and the temperature shifts as a function of concentration for the AC* phase transition in a binary mixture, using our mean field model with the biquadratic P-2 theta(2) coupling - and also with the bilinear P theta and P-2 theta(2) couplings. By expanding the free energy in terms of the tilt angle and polarization, the tilt angle and the temperature shift, are evaluated by using the coefficients given in the free energy expansion. By employing a concentration-dependent coefficient, the tilt angle and the temperature shift are calculated as a function of concentration of 10.O.4 for the SmAC* transition in a binary mixture of C7 and 10.O.4.
