Yields and energy spectra of light charged particles emitted in neutron induced fission of ²³⁵U

Abstract

The yields and energy spectra of light charged particles emitted in the fission of ²³⁵U have been measured in the neutron energy range of 100 keV to 1 MeV. The yield of long range alpha particles is found to increase around 200 keV neutron energy compared to thermal fission. A low energy component observed in the energy spectrum was assigned to the tritons emitted in fission. The yield of this triton component is seen to have a marked increase around 500 keV. These results indicate that LCP yield is influenced by the transition state level characteristics.
