    Notes: Abstract The yields of the long-range α-particles (LRA) in the thermal neutron induced fission 0f233U,235U, and239Pu have been determined relative to the corresponding binary fiassion yield. The measurements were performed with surface harrier detectors on a thermalized reactor beam. We obtained for233U,235U and239Pu binary-to-LRA ratios the values 485±20 respectively 615±20, 475±20. Some of the discrepancies between the published data were explained and experimental indications for235U(n, α)- and239Pu(n, α)-reactions are present. Finally the LRA-yield was correlated with some other fission characteristics.

    Search for the (n th, α) reaction on180Hf,181Ta and209Bi (1978)

    Notes: 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.
