| Abstract: | A rotating drum system was used to search for an 80 ms spontaneous fission (sf) activity in the reaction of 15N with 249Bk. No such activity was found beyond a cross section limit of 0.5 nb. A sf activity with a half-life of 23 ± 2 ms and a maximum formation cross section of 19 ± 4 nb at 82 MeV was observed. The identity of this activity has not been determined. |
