Title: Distortion of pulse-height spectra of neutron capture gamma rays

Abstract

A distortion of pulse-height spectra of neutron capture {gamma}-rays caused by {gamma}-flash at neutron time-of-flight (TOF) measurement using a pulse neutron source has been investigated. Pulses from C6D6 detectors accumulated by flash-ADC were processed with both traditional analog-to-digital converter (ADC) and flash-ADC operational modes. A correction factor of {gamma}-ray yields, due to baseline shift, was quantitatively obtained by comparing the pulse-height spectra of the two data-collecting modes. The magnitude of the correction factor depends on the time, which passed after {gamma}-flash, and has complicated time dependence with a changing sign.
