Americium isotope Am 241 was identified by a group of researchers at the University of Chicago in 1944 and was the fourth trans-uranium element to be discovered, via successive neutron capture ...

For decades, deep space exploration has depended on a handful of obscure isotopes quietly heating small nuclear batteries on robotic probes. Now a different, even less familiar element is moving to ...

A newly proposed approach aids chemical studies of rare, toxic, radioactive, and precious isotopes by requiring 1,000 times less material. Studying radioactive materials is very difficult due to the ...

Lawrence Livermore scientists, in conjunction with international researchers, have discovered five new atomic nuclei to be added the chart of nuclides. The study, conducted this fall, focuses on ...
