Abstract

The decay properties of theJ π=1/2+,E exc=1,098 keV state in203Bi were studied. The state was populated via the204Pb(p, 2n) reaction and the activity was studied with the ion guide isotope separator on-line system IGISOL. The half-life of the 1/2+ state was measured to beT 1/2=303 ±5 ms. From this value the partial half-lives of the three depopulating branches 1/2+ →7/2 (E3), 1/2+→5/2 (E3 +M2) and 1/2+→9/2 g.s. (M4) were deduced. Since all the transitions are configuration forbidden in first order, a detailed study of second-order shell-model configuration mixing could be performed.
