ments which you do determine currently by reactions other than neturon capture reactions.LEDDICOTTE.-At present, the only trace element which we determine by a reaction other than a neutron capture reaction is sulfur. In the n-p reaction, sulfur will produce phosphorus-32. This reaction allows us to achieve a greater sensitivity for sulfur since the sensitivity for the n-gamma reaction on sulfur is limited by t,he length of time necessary for irradiation (usually 2 to 3 weeks) and the fact that the radiations from sulfur-35 are quite low in energy and aren't readily detectable.
