Abstract
Elastic constant measurements for the LaAgxIn1-x system are presented. For large x(x approximately 0.9) the strong softening of the c11-c12 mode can be quantitatively interpreted with a strain-5d band deformation potential coupling. For smaller x(x<or approximately=0.8) strong strain-internal displacement coupling seem to be important.Keywords
