The l-forbidden 1i11/2 --> 2g9/2 M1 transition in 209Pb
Abstract
The mean lifetime of the 0.78 MeV first excited state in 209Pb was measured by the recoil distance method to be τm = 11.1+/-1.3 ps. The B(M1) for the l-forbidden transition is in good agreement with one of several recent theoretical predictions.
