Abstract
THE two known isotopes, Li6 and Li7, have been separated in quantities of the order of one microgram by two separate methods depending on the passage of several microamperes of lithium ions through electric and magnetic fields. The separate isotopes were collected on metal discs cooled with liquid nitrogen, and after fixation by exposure to hydrochloric acid gas, were bombarded by protons and. by diplons in an apparatus already described1. It was possible to observe several hundred disintegration particles each minute from the Li7 targets and about half that number from the Li6 targets arranged to contain about the same number of atoms. The results are summarised in the accompanying table.
