ANS webinar to focus on low-dose radiation risk
Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.
Register now to attend the webinar.

The accuracy of cross sections given by theoretical calculations is evaluated on the collision processes of molecular ions and electrons. The processes focused on are dissociative recombination, dissociative excitation, and rotational and vibrational transitions of the molecular ions of H2+, HeH+ , and their isotopes, which are relevant to divertor plasmas. Adopting the multichannel quantum defect theory, we calculated the state-selective cross sections for various states and energies. The validity of those calculations is investigated by comparing with experimental data under some limited conditions, and the calculations are verified from physical viewpoints.
