Transmutations of Nitrogen by Deutons

Nitrogen bombarded by deutons emits three alpha-particle and two proton groups. For deutons of maximum energy 1.4 mv traversing an air target the alpha-particle groups have ranges of 6.9, 7.8 and 12.7 cm. The reaction involved is ${\mathrm{N}}^{14}$+${\mathrm{D}}^2$→${\mathrm{C}}^{12}$+${\mathrm{He}}^4$, and the transmutation energy, derived from the long range group, in conjunction with the precise mass spectrograph determinations of ${\mathrm{D}}^2$, ${\mathrm{He}}^4$ and ${\mathrm{C}}^{12}$ yields for the mass of ${\mathrm{N}}^{14}$ the value 14.0069. The 6.9 and 7.8 cm groups indicate the existence of excited levels in ${\mathrm{C}}^{12}$ at 3.8 and 4.7 mv. The proton groups from a thin air target bombarded by 1.25 mv deutons have ranges of 24 and 85 cm. The reaction involved is ${\mathrm{N}}^{14}$+${\mathrm{D}}^2$→${\mathrm{N}}^{15}$+${\mathrm{H}}^1$. The transmutation energy of this reaction yields for the mass of ${\mathrm{N}}^{15}$ the value 15.0041. The 24 cm group indicates an excitation level in ${\mathrm{N}}^{15}$ at 4.7 mv. For 1.2 mv deutons, the effective nuclear collision cross sections for the alpha-particle and proton reactions are about ${10}^{-27\mathrm{}}$ ${\mathrm{cm}}^2$ and 3 × ${10}^{-29\mathrm{}}$ ${\mathrm{cm}}^2$, respectively.
