Trajectory calculations were performed using the three-point-charge model. The input parameters took values distributed over a wide range. Using experi mental distributions, each trajectory was assigned a ‘weight’; and the trajectories and their statistical ‘weights’ were used in obtaining initial distributions which in turn reproduced other experimental distributions, such as the angular distribution ofα-particles, very well. Some information about the initial distributions has been obtained. The effect of the anticorrelation, between the finalα and fragment energies, on the initial distributions has been examined.

The yields and energy spectra of light charged particles emitted in the fission of²³⁵U 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.
