利用全吸收技术测量了核反应堆中衰变热的重要贡献者、核和核的进料概率。为了获得非常高等压纯度的源，我们首次将全吸收光谱仪与潘宁阱耦合在一起。我们的结果解决了长期存在的4-3000 s范围内衰变热成分差异的重要部分。
Thefeeding probability of,, andnuclei, which are important contributors to the decay heat in nuclear reactors, has been measured using the total absorption technique. We have coupled for the first time a total absorption spectrometer to a Penning trap in order to obtain sources of very high isobaric purity. Our results solve a significant part of a long-standing discrepancy in thecomponent of the decay heat forin the 4–3000 s range.
