The age of fission neutrons to indium resonance energy has been measured in AGOT graphite using the point source technique. Corrections to the data arising from the following factors were investigated: (a) source and foil size, (b) finite dimensions of medium, (c) higher and/or lower energy activations, and (d) foils are not scaler flux detectors. The age was determined to be 307.8 cm² ± 2.0 cm² and the fourth and sixth moments were 6.577 x 10⁶ cm⁴ and 3.843 x 10¹⁰ cm⁶, respectively. These compare favorably with the values of 307.4 cm², 6.590 x 10⁶ cm⁴, and 4.006 x 10¹⁰ cm⁶ obtained by Monte Carlo calculations.
