WebHowever, neither the fast nor the thermal fission yield of this isotope has 'been measured. Of the various analytical techniques which have been used previously to determine fission yields, e. g., mass spectrometry, spectrophotometry, and radiochemistry, none is applicable to the determination of praseodymium-141. Nuclear fission splits a heavy nucleus such as uranium or plutonium into two lighter nuclei, which are called fission products. Yield refers to the fraction of a fission product produced per fission. Yield can be broken down by: 1. Individual isotope 2. Chemical element spanning several isotopes of different mass number but same atomic number.
