Hello
very interesting topic.
At the moment, the cross sections are not available to users.
Can I revert the question: would you be interested in tampering with them AND
helping us in making available the algorithms to all users? We could
provide you some hooks to modify cross sections and/or angular
distributions.
Let me know
