Deuteron Bombardment ofC14

Bombardment of ${\mathrm{C}}^{14}$ by deuterons produces three nuclear reactions, yielding neutrons, $\alpha$-particles, and protons, and leads thereby to the formation of ${\mathrm{N}}^{15}$, ${\mathrm{B}}^{12}$, and a new radioactive isotope, ${\mathrm{C}}^{15}$. The half-life of this sixth isotope of carbon is 2.4 sec., and the end point of the $\beta$-ray spectrum lies at 8.8 Mev.
