Biography

On December 6, 2006, he claimed discovery of the long-sought

subatomic particle. The discovery involved Jain's use of 3-dimensional photographic medium targets in heavy-ion particle accelerators; modern detectors using electronic sensors were unable to detect the axion due to the very short distances and times involved, but the physical medium was able to identify about 1,200 Axion traces over years of experiment. Jain was one of the few working physicists with experience with that type of detector, which had been largely abandoned in favor of the modern electronic detectors. He was born in India, and received his M.A. at
