Abstract

In the proton-induced fission of ${}^{232}{Th}$ , a binary structure was observed in the velocity and the total-kinetic-energy distributions of fission fragments with A=128–131. From the present results, it is concluded that there are at least two kinds of scission configurations: elongated shapes probably associated with the symmetric liquid-drop path, and more compact shapes associated with the asymmetric shell-influenced path.
