Prompt Fission

In a recent measurement of prompt γ rays from the spontaneous fission of 252Cf an experimental setup was chosen that allowed the study of angular correlations between γ rays and the nuclei from which they were emitted. The observed angular distribution of prompt fission γ rays was then analyzed to estimate the relative contributions from radiation of different multipolarity. Preliminary results are presented and compared to previous angular correlationmeasurements from different fission processes and recent results from calculations with the Monte Carlo Hauser-Feshbach code FIFRELIN.

Transmission data taken at both the 80 and 200 m stations of the Oak Ridge Electron Linear Accelerator have provided resonance parameters for 90Zr to 300 keV bombarding energy. The average s-wave parameters obtained were: <D> = 8�6�1�6keY and So = (0�S4�0�14)x10-4 , while the average parameters for the two p-wave sequences were: for P1/2, <D> = 8�6 � 1 . 6 keY and SI = (3�9�1�0)x 10-4 ; for P3/2, <D> =o4�3�0�S keY and SI = (4�3�0�8)x 10-4 ?

The neutron capture cross section of 137Ba has been measured to high resolution (AE/E ~ o� 2 %) below En = 60 keY. Average values of resonance parameters, extracted for resonances in the range 2�7 < En < 12 keY, are as follows: s-wave level spacing <D) = 380� 70 eV; s-wave radiative width <Tv). = 80�15meV; s-wave neutron strength function 104 So = 0'57�0'2; and p-wave neutron strength function 104 S1 = 0�45�0�2. The s-wave radiative width and the s-wave neutron strength function appear to be lower for 137Ba than for the other barium isotopes.
