Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

The four neutron groups populating the ground state and the lower three excited states of 28Si were studied with a stilbene neutron spectrometer. Total neutron cross sections were obtained from measurements at detection angles of 0, 45, 90, and 135 deg. A large number of resonances were seen, indicating many levels in 29Si. By using the reciprocity theorem, the cross sections for 28Si(n,α0)25Mg reaction were obtained and compared with those given in the literature.
