The Neutrons from the Disintegration of the Separated Isotopes of Magnesium by Deuterons

Abstract

When ${\mathrm{Mg}}^{25}$ is irradiated by deuterons, four groups of neutrons appear from which nuclear energy levels are deduced in ${\mathrm{Al}}^{26}$ at 2.00±0.18 Mev, 3.63±0.18 Mev, and 5.13±0.18 Mev. The $Q$-value for the formation of ${\mathrm{Al}}^{26}$ in the ground state is 5.58±0.10 Mev. From the disintegration data, the mass of ${\mathrm{Al}}^{26}$ is calculated to be 25.9935±9×${10}^{-4\mathrm{}}$ mu.
