Abstract
The elastic constants of krypton single crystals near the triple point determined from neutron-scattering measurements by Skalyo and Endoh and from our Brillouin-scattering measurements differ by as much as 12%. It is suggested that these large differences arise from the different velocities of zero and first sound.Keywords
