ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

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.

Operation of thermonuclear reactors will require knowledge of numerous cross sections for electron interaction with atoms and molecules, largely unknown at present and difficult for experiments. Theory is needed, but first it has to be verified on laboratory-accessible targets. A few working hypotheses and systematic approaches for various electron scattering processes are recommended. We discuss briefly analogies between total cross sections for scattering on nonpolar (BF3, CO2), polar (H2O, NH3, PF3), reactive (BCl3, HCl), and hexafluoride (SF6, WF6) molecules. For partial cross sections (ionization, elastic, electronic excitation), we search for some partitioning schemes. Similarly, we treat the vibrational excitation at shape resonances in linear triatomic molecules (N2O, CO2, OCS). Electron attachment for targets such as CCl4 or CF3I rises quickly toward the zero-energy limit; semiempirical approaches fail, but new theories work well. The paper, in general, shows ways to multitask construction of cross sections rarely measured in laboratories.
