Attenuation of ultrasound has been measured in the intermediate state of single crystals of tin at 3.3 MHz in the temperature range 1.5-3.7 K. A small measurable change of the frequency v o of the collective modes of excitations has been observed very near the critical magnetic field.
This is a striking example of the effect of a Brillouin Zone overlap on the lattice constant of a solution since addition of divalent magnesium to monovalent lithium increases the electron-atom ratio. It may be readily shown4 that the first Brillouin Zone overlap in the BCC structure occurs at e/&%1
