Abstract
The (n th,α) reaction on180Hf,181Ta and209Bi was studied at the thermal neutron guide of the Grenoble high flux reactor. Upper limits ofσ α ≦13μb, ≦μb and ≦0.3μb, respectively, were obtained for the a branches to the ground states in contrast to the values of ≈100μb to ≈500 mb reported in the literature. Possible reasons for these discrepancies are discussed. Furthermore, the present upper limits of the cross sections are compared with the values calculated from the statistical model.
