Neutron production in (alpha,n) reactions: where we were and where we are now

Not scheduled


Prof. Vitaly Kudryavtsev (University of Sheffield)


Neutron-induced background may cause problems for many underground experiments looking for rare events. A number of computer codes are available to calculate cross-sections of (alpha,n) reactions, excitation functions and neutron yields. We have used EMPIRE2.19/3.3 and TALYS1.9 to calculate neutron production cross-sections and excitation functions, and modified SOURCES4 to evaluate neutron yields and spectra in different materials relevant to high-sensitivity underground experiments. We will report here a comparison of different models and codes with experimental data, to estimate the accuracy of these calculations.
