Abstract : Although work has been by Macklin and Gibbons at Oak Ridge on neutron capture cross sections in the 1 to 100 keV range for application to the s-process of nucleosynthesis in stars, much research in this and related fields is still needed. At Los Alamos, Seeger has continued his important studies of the unstable neutron-rich nuclei but more experimental and theoretical work is required to reach an understanding of the r-process of nucleosynthesis. At Rice University, Clayton has analyzed the empirical data needed to reach a more complete understanding of the chronology of nucleosynthesis in the Galaxy. At the California Institute of Technology, studies continue on reactions such as C13(Alpha,n) which serve as sources of neutrons in stars. The situation as of March, 1968 is reviewed with especial emphasis being placed on the correlation of astrophysical and geochemical observations with predictions based on experiment and theory in neutron physics.
