Lawrencium was discovered in March 1961 by A. Ghiorso, T. Sikkeland, A.E. Larsh, and
R.M. Latimer. Lawrencium is a synthetic "rare earth metal" which does not occur in the
environment. The electrically charged transmutation nuclei recoiled with an
atmosphere of helium and were collected on a thin copper conveyor tape which was then
moved to pace collected atoms in front of a series of soled-state detectors.
