Abstract

Neutrons produced in spontaneous fission processes and (alpha,n) reactions can induce background events in underground experiments looking for rare processes. A number of computer codes are available to calculate cross-sections of (alpha,n) reactions, branching ratios to various states and neutron yields. SOURCES4 code has been used in this work to calculate neutron yields and energy spectra with input cross-sections and branching ratios taken from experimental data and models from EMPIRE2.19/3.2.3 and TALYS1.9 codes. A comparison of SOURCES4 calculations with experimental data from alpha beams and radioactive decay chains are presented.

Strengths

Giving the availability of different tools for simulations authors present optimised version of one of them - SOURCES4 code and comparison with other s and available data. Optimisation of this code (version 4A) thanks to including data from experiments and models from two other code gives important possibility to have a reliable simulation of neutron production in extended energy range.

Would this version of the code be published for common use?

Report

I would like to thank the reviewer for positive comments.
Concerning availability of the code for common use, my approach has always been the same. Since none of us (authors of this or previous publications) has been an author of the original code, we cannot really distribute the code ourselves. A user will need to request the code (and most likely pay for it) from Oak Ridge library (the fee is for library maintenance, not for the code itself). After that I can send updated libraries of cross-sections and branching ratios (for free) to the user on their request.
