Prof. Anton Tonchev’s article “Precision Photo-Induced Cross-Section Measurement Using the Monoenergetic and Polarized Gamma Beams at High Intensity Gamma-Ray Source” was highlighted by the 2011 Stewardship Science Academic Alliances Annual as a “Publication Contest Winner”. Prof. Tonchev received a three-year award of $900,000 through the Stewardship Science Academic Alliances Program in 2009. The aim of this research activity is to use the novel source of γ-radiation at the High Intensity Gamma-ray Source (HIGS) facility for precision (γ,γ’) and (γ,xn) cross-section measurements on actinide nuclei. A systematic and complete survey of excited states in 239Pu, 233U, and 23 7Np is currently being carried out at HIGS at energies below the particle emission threshold. The goal of these studies is the identification of dipole states which are strongly coupled to the ground state.
