On Beam Study of 198Bi Decay

Excited nucleus 198Bi was produced via the 187Re(16O, 5n)198Bi reaction. The γ-rays following the β+ /EC (electron capture) decay of 198Bi were measured in beam by using a powerful multidetector system. Based on coincidences with the known γ-rays of 198Pb, five new transitions were identified and eight new energy levels were established for 198Pb.
