INELASTIC NEUTRON-SCATTERING FROM THE SPIN-GLASS CU0.95MN0.05 - COMPARISON BETWEEN TIME-OF-FLIGHT AND 3-AXIS TECHNIQUES

Measurement were performed at 5 and 300 K. The strong quasi-elastic scattering could be described by a Lorentzian centered at zero energy transfer and deformed by the detailed balance factor. The signal-to-background ratio is better by a factor of 2 in TAS, while the measuring time is about 3 times longer in TAS than in TOF. © 1979.
