Description
Experimental data on photoneutron spectrum for reaction of 16.6MeV mono-energetic polalized photons on medium-heavy mass targets were obtained at BL-01, NewSUBARU, Hyogo, Japan. The data consists of low energy neutrons having energy distribution similar to tail of Maxwellain and relatively high energy ones originated from decay of pre-equilibrium status. In this presentation, quantities characterized the spectrum shape are presented as a function target mass. The discussions on the parameters expressing ratio of neutrons from pre equilibrium to equilibrium states are presented in comparison with past experimental data.
