Uranium has two primordial isotopes (uranium-238 and uranium-235). Uranium-238 has 92 protons plus 146 neutrons and uranium-235 92 protons and 143 neutrons.Pallava Bagla/Getty Images Atomic mass (ma) is the mass of an atom. Asingle atomhas a set number of protons and neutrons, so the ...
A MultiPhoton-Ionization Time-Of-Flight Mass Spectrometry (MPI/TOFMS) apparatus was developed for real-time measurement of the uranium isotopic ratio in nascent UF 5 formed by the 266 nm photolysis of effusive UF 6 ( < 300 K, ≈ 1.3 × 10 4 Pa). The UF 5 was selectively and efficientl...
