Direct identification of Ac and No molecules with an atom-at-a-time technique

Nature, Published online: 04 August 2025; doi:10.1038/s41586-025-09342-y

Mass number measurements of the molecular species produced when ions of actinium (Ac) and nobelium (No) are exposed to trace amounts of H2O and N2 demonstrate direct species identification using an atom-at-a-time technique for heavy elements.
