Peak Separation from Time-of-Flight Spectra and Problems of Detector Efficiency Determination in Neutron Spectroscopy

摘要

An analytical expression for real neutron line representation is discussed in detail. In connection with elastic peaks from a small carbon sample this function can give a convenient model line to separate elastic peaks from continuous spectra. This problem is also discussed. Using the 252-Cf method for efficiency determination the experimental points have to be continued to higher energies. Related problems are discussed and illustrated by examples.
