Abstract The elastic constants of GaN have been determined using Brillouin scattering; in GPa they are: {ital C}{sub 11}=390, {ital C}{sub 33}=398, {ital C}{sub 44}=105, {ital C}{sub 66}=123, {ital C}{sub 12}=145, and {ital C}{sub 13}=106. Our values differ substantially from those quoted in the literature which were obtained from the determination of mean square displacement of atoms measured by x-ray diffraction. {copyright} {ital 1996 American Institute of Physics.}
