Abstract
Measurements of the coherent scattering amplitudes of various mixtures of heavy and light water are reported. By means of mirror reflection technique the coherent scattering amplitudes of the D2O and H2O molecule are determined to be 19.148±0.004 F and -1.679±0.004 F, respectively. Use of aH=-3.740±0.003 F, obtained by the same technique, yields aD=6.674±0.006 F as the bound scattering amplitude of the deuterium nucleus. This value disagrees with the widely accepted 6.21±0.04 F, reported by Bartolini et al. in 1968.Keywords
