| Abstract | The average energy and multiplicity of prompt $\gamma $-rays from slow neutron-induced fission of $^{235}$U have been measured using the STEFF spectrometer at the neutron time-of-flight facility n_TOF. The individual responses from 11 NaI scintillators were corrected for multiple $\gamma $-ray interactions, prompt fission neutrons and background counts before being deconvolved to estimate the emitted spectrum of prompt fission $\gamma $-rays. The results give an average $\gamma $-ray energy ${\bar{E}}_{\gamma }$ of 1.71(5) MeV and multiplicity $\bar{\nu }_{\gamma }$ of 2.66(18) considering $\gamma $-rays emitted within the energy range 0.8–6.8 MeV. The n_TOF data has a slightly larger ${\bar{E}}_{\gamma }$ and smaller $\bar{\nu }_{\gamma }$ than other recent measurements, however the product of the two is in agreement within quoted uncertainties. |
