Abstract
The paper describes the production of a tracer packet of heavier rare earth elements containing carrier-free radionuclides of 153,155Tb, 153,155,157Dy, 159Ho, 159,161Er, 161Tm produced by medium energy 7Li and 12C irradiation on an europium oxide target and the subsequent separation of bulk europium from the carrier-free products.
