12B(n,γ) - The influence on r-process nucleosynthesis of light elements

Document Type

Conference Proceeding

Publication Date



Because of interest in the 11,12B(n,γ) reaction in seeding r-process nucleosynthesis through light neutron-rich nuclei, we have measured the 12B(d,p) reaction for the first time using the ATLAS in-flight facility at Argonne National Laboratory. We also measured the 11B(d,p) reaction in the same way for calibration. The spectroscopic factors of excited states and the branching ratio of the neutron-unbound state in 12B are obtained from the current experiment and the reaction rate for 11B(n,γ) is discussed in comparison with the theoretical prediction. © 2009 American Institute of Physics.
