This grant to the University of Texas at Austin provides for start-up equipment and expenses for an experiment designed to measure the mass of neutrinos from the beta decay of tritium. The experiment will be carried out using an electron lens spectrometer of unique design. The upper limit on the mass of tritium beta decay neutrinos to be attained in this experiment is expected to be below 5 eV.

这笔给德克萨斯大学奥斯汀分校的赠款提供了启动设备和实验费用，该实验旨在测量氚的贝塔衰变产生的中微子的质量。这项实验将使用设计独特的电子透镜光谱仪进行。在这个实验中，氚-贝塔衰变中微子的质量上限预计将低于5 eV。
