文摘

While carrying out these experiments we have determined the acoustics velocities in Bi12SiO20:Fe. The frequencies of the longitudinal and transversal waves which propagate in the crystal have been calculated. The elastic modules and the coefficients of the Christoffel determinant are also presented.
