Structure in the ${}^{14}C$ + ${}^{16}O$ reaction cross sections

The yields of several nuclides produced in the

{}^{14}C

{}^{16}O

reaction have been measured over the range

E_{c . m} = 16 - 34

MeV. The excitation function for the production of

{}^{22}{Ne}

displays a regular sequence of narrow fine-structure resonances similar to those previously observed in the

{}^{12}C

{}^{16}O

reaction. This is the first time that such structure has been observed for systems of non-

α

-particle nuclei. Intermediate-width resonances are observed in the yield of

{}^{18}O

E_{c . m} = 19.5, 23.5, 27.5, and 31

MeV. Correlated structure appears in the inelastic scattering cross section to the

3^{-}

state of

{}^{14}C

at all these energies, except possibly

E_{c . m} = 19.5

MeV. The resemblance of the 23.5-MeV structure to anomalies previously observed in the

{}^{16}O

{}^{16}O

and

{}^{12}C

{}^{16}O

reactions is noted, and some properties of the compound system are deduced.
