Calculations on the time-dependent neutron spectra in an ice block are reported for the temperature range of 8616 K.<BR>Three models for the lattice vibrational frequency distributions were applied to calculate scattering kernels. Calculated spectra were compared with measured spectra. It was found that the calculation with the Debye model agrees well with the experiment.<BR>From the present analysis, it was suggested that the Debye temperature Θ<SUB>D</SUB> of the low temperature ice can be expressed as Θ<SUB>D</SUB> = 208 + 0.3T<SUB>O</SUB> where T<SUB>O</SUB> is the medium temperature.
