In the present paper we have applied an Extended Three-Body Force Shell Model (ETSM) to investigate the elastic properties of mixed alkali cyanide-alkali halide crystal KCNxCl1-x for x= 0.41, 0.56, 1.0 at different temperature. This model includes the effect of coupling between the translational and rotational motion of cyanide molecules. The static shear elastic constant c44 obtained by us shows an anamolous behaviour as a function of temperature and followed the same trend as observed experimentally. We have also reported the c11 and c12 of KCNxCl1-x mixed crystal.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
