The non-unique first-forbidden beta decays of Tl-201, Pb-208, and Hg20
6-208 are calculated in terms of the shell model with different intera
ctions and model space. The calculated log f(0)t value very sensitivel
y depends on the effective interactions used in diagonalizing the ener
gy matrix. The beta decay modes for Hg-206 and Hg-208 are also compare
