ONCE-FORBIDDEN BETA SPECTRUM OF Tl$sup 20$$sup 6$

Journal Article · · Physical Review (U.S.) Superseded in part by Phys. Rev. A, Phys. Rev. B: Solid State, Phys. Rev. C, and Phys. Rev. D

The beta spectrum of 4.2-min Tl/sup 206/ was investigated in a 4 pi scintillation spectrometer. The source was in secular equilibrium with the 2.6 x I0/sup 6/ year Bi/sup 210/ parent. The electron distribution was observed to have a nonstatistical form which could be fitted with a once forbidden pseudovector shape factor. No necessity for the inclusion of any pseudoscalar contribution was observed. The energy release in the Tl/sup 206/ decay is l.571 plus or minus 0.010 Mev. (auth)
