Nuclear data evaluation of the $$^7$$Li(p,xn) reaction for incident energies up to 200 MeV

Matsumoto, Yuiki*; Watanabe, Yukinobu*; Kunieda, Satoshi  ; Iwamoto, Osamu  

Neutron emission from the $$^7$$Li(p,n)$$^7$$Be reaction can be divided into two components: a mono-energetic component for the transition to the ground and the 1st excited states and a continuum component formed by $$^7$$Li breakup processes. For the former, we have obtained the differential cross sections by interpolation based on Legendre fitting of available experimental data up to 45 MeV and apply DWBA calculations above 45 MeV. Next, we have applied the CCONE code to DDX calculations of the continuum component, and adjusted pre-equilibrium model parameters to reproduce experimental data well. Finally, both the results are merged and then the evaluated DDX data are completed.
