Abstract
An investigation of the relative deuteron/proton yield from sulfur, produced by irradiation with the Iowa State College 65-Mev synchrotron, was made by employing a 12-inch, helium-filled, magnetic cloud chamber as the means of detection. The average curvature and the range of each acceptable track were measured and were used to find an experimental mass histogram that provided a clear indication of proton and deuteron groups. Analysis of the mass histogram produced a ratio of deuterons to protons of 0.19±0.04. It is estimated that the corresponding ratio for an infinitesimally thick target is 0.15±0.04.
