Abstract
The Pendellösung fringe structure within the Bragg reflection from perfect crystals of germanium has been studied over a wide interference range using full-spectrum incident neutron radiation. After allowing for the effects of residual crystal curvature, the experimental data yield a precision determination of the crystal structure amplitude. The coherent nuclear scattering amplitude for germanium is determined to be 0.81858 (36) x 10-12 cm.Keywords
