Abstract Sources of187Pb were produced by the142Nd(48Ti, 3n)187Pb reaction followed by online mass separation of the products. Measurements ofγ-γ andα-γ coincidences and half-lives were performed. Twoα-emitting states in187Pb were found with half-lives of 15.2±0.3 s and 18.3±0.3 s, respectively. Theα-γ coincidences yielded excitation energy and possible spin values for a few levels in183Hg. Gamma-transitions in187Tl were identified and a level scheme for187Tl is proposed on the basis of the coincidence relationships and the level systematics of the heavier odd-thallium isotopes.
