Search for the l-forbidden beta decay /sup 207/Tl. -->. /sup 207/Pb(570 keV)

Journal Article · · Phys. Rev. C; (United States)
We have searched for the l-forbidden beta decay of /sup 207/Tl to the first excited state of /sup 207/Pb by looking for 570-keV ..gamma.. rays following the decay of /sup 207/Tl. We find a branching ratio of (2.4 +- 5.6) x 10/sup -7/ per /sup 207/Tl decay. This limit could provide a test for calculations of core polarization, meson exchange, and ..delta.. excitation effects. We also find a branch of (0.54 +- 0.05)% for the l-forbidden M1 transition /sup 207/Pb(898,(3/2/sup -/..-->..570,(5/2/sup -/) and measure the intensities of ..gamma.. rays emitted following the decay of /sup 211/Pb.
