Until now, it has not been clarified why the fission product of ^<235>U induced by thermal neutrons shows two peaks. It is possible to explain this problem by the present idea of channel-dependent fission barrier introduced by the selective channel scission (SCS) model. Fission of ^<235>U induced by thermal neutrons was analyzed theoretically by the SCS model. Using the SCS model the fission barrier of each scission channel is calculated. If the excited energy of the nucleus is more than some of the channel-dependent fission barriers, those channel scan be opened to achieve fission. It is understood that the distribution of fission barriers results in two peaks for ^<236>U. Hence, the distribution of fission products from thermal neutron fission of ^<235>U also gives two peaks. It is known that fission products are almost stable isotopes at the peaks. If the nucleus can be excited at a lower energy level than that by thermal neutrons, cleaner fission of ^<235>U is possible.
