Elements of X-ray DiffractionThis is a reproduction of a book published before 1923. This book may have occasional imperfections such as missing or blurred pages, poor pictures, errant marks, etc. that were either part of the original artifact, or were introduced by the scanning process. We believe this work is culturally important, and despite the imperfections, have elected to bring it back into print as part of our continuing commitment to the preservation of printed works worldwide. We appreciate your understanding of the imperfections in the preservation process, and hope you enjoy this valuable book. |

... relation Exposure = ( intensity of x - ray beam ) ( time ) . Since the time is constant for all the diffraction lines on one film , this means that the photographic density is directly proportional to the x - ray in- tensity . Density ...
