Abstract

A new nuclide ²³⁸Th has been produced via multinucleon transfer reaction by 60 MeV/u ¹⁸ O ion irradiation of natural uranium. The produced thorium was radiochemically separated from the mixture of uranium and its reaction products. The activity of thorium was measured by using a HPGe detector and a planar HPGe detector. ²³⁸ Th has been identified for the first time by measuring the growth and decay of the γ rays from its daughter nucleus ²³⁸ Pa.
