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 ?
