Debye-Sherrer diffraction rings

An exjjerimental device was built several years ago in which a beam of clusters is crossed by an electron beam. The resulting Debye-Sherrer diffraction rings are recorded on a photographic plate. A schematic view of the apparatus is shown in Fig. 1. The chosen compound in the vapor state, at inlet pressure pg and inlet temjjerature Tg, passes through a nozzle, 0.2 mm in diameter, and expands into vacuum in the form of a free jet. During this... 

DEBYE, PETER J. W. (1884-1966). A Dutch chemist and physicist who received the Nobel prize for chemistry in 1936 for his contributions to our knowledge of molecular structure through his investigations on dipole moments and on the diffraction of X-rays and electrons in gases. The interference patterns are still called Debye-Sherrer rings. He also made outstanding contributions to knowledge or polar molecules and to fundamental electrochemical theory.
