【 摘 要 】

This is the final report of a Laboratory-Directed Research and Development (LDRD) project at the Los Alamos National Laboratory (LANL) originally planned for three years. After one year, the project was terminated due to the laboratory-wide reduction in LDRD funding. The goal of the project was to make measurements of the capture of neutrons by unstable nuclei to learn more about the basic process as it relates to the formation of elements in the stars. Detailed measurements on unstable nuclei, of the sort we would make, have not ever been made before, and Los Alamos is presently unique in the world for being able to make them. A flight path was built and the experimental environment was characterized. However, due to the premature termination of this project, we did not achieve most of our goals and no data were obtained on unstable nuclei.
