The phonon spectra of the C-15 phase (Hf/sub 0.5/Zr/sub 0.5/V/sub 2/)H/sub x/ with five different compositions were measured with a Beryllium-Filter-Detector-Spectrometer. It was observed that their phonon spectra vary with hydrogen content. Results show that the change of T/sub c/ with x in the (Hf/sub 0.5/Zr/sub 0.5/V/sub 2/)H/sub x/ system is related to softening of the acoustic branches. This softening of the acoustic branches seems in favor of the increase of T/sub c/, while softening of the optical branches may suppress its superconductivity.
