Abstract

A counter method offering a more convenient and flexible measurement of neutron energy in the medium to high energy range is further described. Experimental results obtained by the application of this method to the reactions $A^{40} (d, n)$ and $N^{15} (d, n)$ are given.

For the argon reaction, $Q$ -values of 5.97, 4.63, 2.87, and 1.57 Mev were observed. The $K^{41}$ — $A^{40}$ mass difference was thus observed to be 0.99936±0.00027 MU.

For the nitrogen reaction, $Q$ -values of 10.9, 4.8, 1.6, and 0.2 Mev were observed, the last value being in some doubt.
