Total Cross Sections of Chlorine, Sodium, Titanium, and Bromine for Fast Neutrons

Abstract

Relatively new liquid scintillation counter methods were adapted to detect fast neutrons with a heretofore unattailable efficiency of about 19 percent. The geometry obtained was the so-called "good" geometry, which was a half-angle at the counter of 2.7°. With the more efficient counter reasonable counting times could be obtained with the detector subtending a half-angle of only 2.7° from the target.
