Verification of the pulse height tally in MCNP 5

Pulse height tallies are commonly used in Monte Carlo codes to predict detailed measured photon spectra for spectrometry purposes. The pulse height tally is unique among the various tallies in MCNP. Unlike flux or current tallies, which are calculated as soon as the particle exits or collides in the cell, the entire set of tracks for a history must be completed before the pulse height tally can be made. The objective of this work was to verify the pulse height tally and prepare to verify the new MCNP 5 variance reduction features with the pulse height tally. In this paper, we give details to the analytic solution of the pulse height distribution using a modification to Shuttleworth's fictitious elements, report MCNP 5 results for the pulse height tally, energy deposited and current tallies for the problem
