The 2025 ANS election results are in!
Spring marks the passing of the torch for American Nuclear Society leadership. During this election cycle, ANS members voted for the newest vice president/president-elect, treasurer, and six board of director positions (four U.S., one non-U.S., one student). New professional division leadership was also decided on in this election, which opened February 25 and closed April 15. About 21 percent of eligible members of the Society voted—a similar turnout to last year.

Currently the problem of theoretical calculation and experimental determination of the isotopic exchange rate in mixes of hydrogen isotopes is open. There are a few experimental data on exchange rate constants that are rather discrepant. Of interest are experimental data on isotopic exchange rate in a gaseous mix of hydrogen isotopes at high pressures (thousands atmospheres). Raman spectroscopy is a relevant method for obtaining objective data on isotopic exchange rate in a gaseous mix of hydrogen isotopes, since it allows one to determine a gaseous mix composition without sampling in a real time. The paper describes equipment which allows registration of Raman spectra for gases under pressure up to 400 MPa and experimental data determining the constants of isotopic exchange rate in a protium-deuterium mix at pressures up to 200 MPa.
