WebUranium 234. L’ uranium 234, noté 234U, est l' isotope de l' uranium dont le nombre de masse est égal à 234 : son noyau atomique compte 92 protons et 142 neutrons avec un spin 0+ pour une masse atomique de 234,040 95 g/mol. Il est caractérisé par un excès de masse de 38 145,0 ± 1,1 keV, et une énergie de liaison nucléaire par ... WebIls ont ensuite testé la présence de protactinium en ajoutant du protactinium 234 à la solution. Lorsque celui-ci s'est précipité, il s'est avéré qu'il était séparé des isotopes de demi-vie de 13 et de 90 min , démontrant ainsi que von Grosse s'était trompé et qu'il ne s'agissait pas d'isotopes du protactinium.
