Targets of 38.7% carbon 14, deposited from a glow discharge in acetylene, were used for the determination of the following threshold energies: C14(p, n)N14, 671.5+/-0.5 kev; C14(p, n)N14*, 3149.6+/-1.1 kev; C14(α, n)O17, 2340+/-3 kev. Corresponding reaction energies are -626.4+/-0.5, -2938.3+/-1.0, and -1820+/-2 kev. The latter two thresholds were detected by the counter-ratio technique. The C14(p, n)N14 excitation curve was extended to 3.4 Mev, covering a resonance at 2908+/-4 kev with a natural width of 71+/-5 kev. Resonance energies agree with previous experimental results but the widths are larger, perhaps due to target thickness errors. Absolute cross sections are compared with those of N14(n, p)C14. Compound nucleus spins and partial widths are calculated. C14(α, n)O17 resonances with energies and natural widths of 2553+/-4, 1.6+/-1 2642+/-3, 10+/-1 (2798+/-11, 22+/-10)? 3335+/-15, 100+/-20 and 3508+/-4, 54+/-3 kev were observed. The 0° differential cross section at 2642 kev is 31 mb/sterad +/-60%. An angular distribution taken at this resonance leads to a total cross section of 300 mb and a compound-nucleus spin of either 1- or 3-. A method is presented for evaluating resonance width, height, and area to find target thickness and natural width.
