Lawrencium was discovered by A. Ghiorso, T. Sikkeland, A.E. Larsh, and R.M. Latimer at Berkeley University in March 1961 by bombarding a mixture of californium atoms with boron ions. At first they assigned the atoms as 257Lr, but after Flerov and associates at Dubna Laboratory were unable to detect the isotope as described by emission and half-life, the assignment was changed to either 258Lr or 259Lr [2].

Origin of name

Named after Ernest O. Lawrence [2]. The name was finalized in 1997 [4]. Originally lawrencium had the Lw [3].
