The mass distribution of the fragments of the fission of 213 At in the reaction 209Bi(a,/) has been measured for a energies in the range 34.7-50 MeV. Over the entire energy range studied, the asymmetric mode is an improbable, slightly energy-dependent mode for the 213At fission. This property of the 213At fission represents a qualitative distinction from the fission of heavy nuclei.
