Popis: The decay scheme of the 2.5 ms isometric state in 208Bi has been established with the aid of high-resolution γ-ray and electron spectrometry. The multipolarity of the 921.0 keV isomeric transition has been determined as E3 and the 1571.1 isomeric state therefore probably has spin and parity 10−. The isomeric transition is hindered by a factor of 3.200 with respect to the Weisskopf estimate. This can be explained as being due to j-forbiddenness.
