The abundance of low energy deuterons and tritons was determined in a nuclear emulsion stack exposed at Fort Churchill, Manitoba, Canada on August 4, 1962 under 4.2 g/sq cm of residual atmosphere. Using the grain density vs. residual range method for the identification of tracks produced by particles, the differential flux of deuterons and tritons was determined. The results appear to be consistent with the absence of deuterons and tritons in the primary cosmic radiation. An upper limit on the amount of hydrogen traversed by low energy cosmic ray particles has been placed. (Author) Supported in part by NASA.
