Elastic scattering /sup 10/B(/sup 14/N,/sup 14/N)/sup 10/B angular distributions were measured at four bombarding energies: 38.1, 42.0, 46.0, and 50.0 MeV. By detecting the recoiling target nuclei complete angular distributions ranging from theta/sub c.m./ = 14/sup 0/ to 176/sup 0/ were obtained. Normalized cross sections, sigma/sigma/sub R/ were found to be larger than 0.1 for angles greater than 160/sup 0/. The anomalous behavior at the backward angles is interpreted as partially due to an elastic ..cap alpha..-transfer process. The deduced spectroscopic factor for the configuration of an alpha particle coupled to a /sup 10/B core in the /sup 14/N ground state is S/sub 4/ = 0.65 +- 0.10. The compound elastic contribution is about 20% of the calculated transfer cross section at theta = 176/sup 0/ and accounts for 3% of the experimental cross section at this angle.
