Abstract
Laser fusion targets consisting of DT gas contained in Teflon‐coated glass microshells produce 14.1‐MeV neutrons that can interact with the 28Si nuclei in the glass to produce radioactive 28Al. Using a very efficient collection‐detection scheme that could detect the decay of 10% of the 28Al created, we identified these nuclei by their 1.78‐MeV γ ray, which decayed with a 2.2‐min half‐life. From the number of 28Al nuclei created and the neutron yield the compressed glass areal density was found to be 0.0059 g/cm2.Keywords
