ANS partners with Discovery Place to engage young learners in nuclear science concepts
Imagine a place where children and adults can learn together about nuclear science as a carbon-free energy source that can be an answer to climate change. Guests can experience a cloud chamber, remotely inspect equipment with a drone, and hold a simulated low-enriched uranium fuel pellet. On Saturday, July 6, such a place actually existed for three hours. That place was the Discovery Place Science Museum in Charlotte, N.C. Ryan Leung, a Discovery Place experience specialist, led a team of local nuclear energy industry volunteers and representatives from the American Nuclear Society and Women in Nuclear to organize and execute an Energy Summit.

The neutron-induced gamma-ray production cross section for the first excited state of l4N was measured for neutron energies from 2.65 to 3.55 MeV at intervals of 100 keV. An angular distribution from 45 to 135 deg in 10-deg steps was measured at an incident neutron energy of 3.45 MeV. Neutrons were produced by the 7Li(p,n)7Be reaction using a pulsed proton beam from the University of Massachusetts Lowell 5.5-MV Van de Graaff accelerator. The interaction of neutrons from the 7Li(p,n)7Be* reaction in the sample was taken into account. A calibrated 235U fission chamber was used to measure the absolute incident neutron fluence. Gamma rays were detected by a Ge(Li) crystal surrounded by a NaI(Tl) anti-Compton annulus. This spectrometer was used in conjunction with the pulsed-beam time-of-flight technique to attenuate background. The measured cross section compares favorably with other experimental data and with the ENDF/B-VI evaluation.
