摘要

A high-resolution inelastic neutron scattering (INS) spectrum has been observed for trans-polyacetylene films in the range 8-4000 cm(-1) at 6 K, and compared with the calculated INS spectrum based on the force field obtained in our previous study. The peak positions as well as the overall intensity profile of the observed INS spectrum are well reproduced by the present calculation, in which the effects of the Debye-Waller factors and the phonon wings are taken into account.
