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.
Division Spotlight
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.

Doppler broadening line shapes of 0.4776-MeV gamma transition of 7Li* populated in the 9Be(n,t1) reaction at 14.9 MeV have been analyzed at 40-, 55-, and 90-deg detector positions in respect to the beam axis for the evaluation of the angular distribution W() of outgoing tritons (t1) after the population of first 7Li excited state. A nonsymmetrical shape of the W() dependence with the Legendre polynomial coefficients A1 = 0.31 ± 0.06 and A2 = 0.23 ± 0.06 has been found. That fact does not support the belief in the simple nuclear reaction mechanism through the single isolated level of 10Be compound. Obtained data are compared with other available experimental results.
