Abstract

The cross section for the $C^{14} (d, γ) N^{16}$ reaction has been measured in the interval $1.2 < E_{d} < 2.6$ MeV by comparing the $N^{16}$ activity with $C^{15}$ activity produced in the ( $d, p$ ) reaction in the same bombardment. The cross section varies about a value of approximately 5 μb and shows several maxima in the region of bombardment. The results are interpreted in terms of compound-nucleus formation; in particular, for the assumed resonance at $E_{d} = 2.0$ MeV, it is found that $Γ_{γ_{T}} \approx 20$ eV. There is no evidence for direct capture, but some contribution from this process cannot be excluded. The half-life of $C^{15}$ was redetermined in the course of the work and found to be 2.49±0.07 sec, a value about 10% higher than that currently accepted.
