Neutron Coherent-Scattering Amplitudes of Ga, In, As, and Sb

Neutron-diffraction data obtained from the compounds GaAs, GaSb, InAs, and InSb lead to the following neutron coherent-scattering amplitudes: fGa=(0.72±0.01)×10^-12 cm, fIn=(0.39±0.01)×10^-12 cm, fAs=(0.64±0.01)×10^-12 cm, and fSb=(0.54±0.01)×10^-12 cm. The data were also used to evaluate the Debye characteristic temperature for the compounds in use; the resulting Debye temperatures are 175^∘{}K for InSb, 240^∘{}K for InAs, 235^∘{}K for GaSb, and 247^∘{}K for GaAs. The neutron wavelength employed was 1.391 {}.
