Abstract
Differential elastic scattering cross sections for neutrons scattered from /sup 13/C have been measured at 9 angles from 20/sup 0/ to 160/sup 0/ for 1.25 MeV< or =E/sub n/ < or =6.5 MeV. These data together with high-resolution total cross section measurements were analyzed by means of a multichannel-multilevel R-matrix program to determine J, r, g/sub lc/, and other parameters of many newly assigned states up to E/sub x/ = 14 MeV in /sup 14/C. This extensive and in-depth investigation of /sup 14/C provided a basis for comparison to nuclear model predictions over a wide range of excitation energy. A core-coupling model was employed to calculate states in /sup 14/C as well as nucleon spectroscopic factors for reactions leading to these states. Calculations of states in /sup 14/C via both effective interactions and a weak coupling model, together with those from the core-coupling model, were compared to results of the R-matrix analysis. Much of the structure observed in the experimental work is predicted by the models.
