Revisiting the 7Li(p,n)7Be reaction near threshold

• We review neutron experimental data for the 7Li(p,n) reaction near threshold.
• A new computational method was used to study all the available published data.
• A consistent description of the neutron source was derived fitting the available data.
• We found that the neutron yield at 0° studied by Kononov is the most sensitive curve.
• A consistent set of parameters to parametrize the Breit–Wigner formula is presented.

In this work we review all the available experimental neutron data for the 7Li(p,n) reaction near threshold which is necessary to obtain an accurate source model for Monte Carlo simulations in Boron Neutron Capture Therapy. Scattered published experimental results such as cross sections, differential neutron yields and total yields were collected and analyzed, exploring the sensitivity of the fitting parameters to the different possible variables and deriving a consistent working set of parameters to evaluate the neutron source near threshold.
