creating neptunium-238. 238 92U + 2 1H → 238 93Np + 2n The neptunium isotope then undergoes β− decay to plutonium-238 with a half-life of 2.099 days

though is not in widespread use as of 2022[update]. The decay chain of uranium-233 forms part of the neptunium series and ends at nearly-stable bismuth-209

in the 1.5-metre (60 in) cyclotron at the University of California, Berkeley. First, neptunium-238 (half-life 2.1 days) was synthesized, which then beta-decayed

method was first applied to the actinides for separating plutonium-239 and neptunium from uranium, thorium, actinium, and the other actinides in the materials
