A webinar, and a new opportunity to take ANS’s CNP Exam
Applications are now open for the fall 2025 testing period for the American Nuclear Society’s Certified Nuclear Professional (CNP) exam. Applications are being accepted through October 14, and only three testing sessions are offered per year, so it is important to apply soon. The test will be administered from November 12 through December 16. To check eligibility and schedule your exam, click here.
In addition, taking place tomorrow (September 19) from 12:00 noon to 1:00 p.m. (CDT), ANS will host a new webinar, “How to Become a Certified Nuclear Professional.” More information is available below in this article.

A total of 22 gamma-ray transitions were measured from (n,n′γ) reactions on the four even-even nickel isotopes, 58,60,62,64Ni. Absolute gamma-ray production excitation functions at 125 deg were extracted for these transitions from their thresholds up to neutron energies of 4 MeV. Inelastic neutron scattering cross sections for 19 levels were inferred from the gamma-ray production data and compared to the Evaluated Nuclear Data File (ENDF/B-IV, MAT 1190). Cross-section agreement for the first excited 2+ states in these four isotopes is generally good, but excitation functions associated with many of the higher excited states in nickel are in strong disagreement with the file.
