Abstract The angular distribution of conversion electrons from the 4+→2+ transition in the ground-state rotational band of240Pu has been measuredvia the238U (α,2n)240Pu reaction. The electrons are emitted in flight from the Pu nuclei recoiling into vacuum atv/c≅0.2%. The attenuation of the angular distribution by extranuclear fields is found to be less than 20% within 120 ps. The hyperfine interactions are discussed with particular attention to the high charge states of actinide recoil ions following internal conversion. Charge distributions ranging up to 45+ have been observed for240Cm nuclei in the239Pu(α,3n) reaction.
