Popis: |
Inelastic neutron scattering spectra of α-MgH 2 powder have been measured at T = 7 K with an energy resolution better than 1.5% using the time-of-flight direct geometry spectrometer SEQUOIA. Based on these spectra, the density g ( E ) of phonon states in α-MgH 2 has been experimentally constructed for the first time. Comparing the available experimental data on the heat capacity of α-MgH 2 with those calculated using the obtained g ( E ) confirmed the good accuracy of its determination. |
