text: The isotope they discovered, einsteinium-253, has a half-life of about 20 days and was produced by combining 15 neutrons with uranium-238, which then underwent seven beta decays.
text: At the same time, neutrons in the newly formed atoms' nuclei underwent beta decay, producing an electron and a proton.
text: He discovered the isotope 253Es (half-life 20.5 days) that was made by the nuclear fusion of 15 neutrons with 238U (which then went through seven beta decays).
text: The new element was produced by the nuclear explosion in miniscule amounts by the addition of 15 neutrons to uranium-238 (which then underwent seven beta decays).
