The angular correlation function between the deexcitation gamma ray and protons inelastically scattered from the first excited state (4.43 Mev.) in C/sup 12/ was measured for six different proton scattering angles. These angles were 18, 30, 45, 60, and 110 degrees in the laboratory system. The angular correlation function was found to be of the form W( /sub gamma /) = A + B sin/ sup 2/ 2 /sub gamma / - /sub s/) wh ere /sub s/ is the symmetry angle and was found to be approximately, but not exactly, equal to the classical recoil angle. The A/B ratio was found to be approximately equal to 0.5. Measurements were also taken for the azimuthal angular correlation function. The dath were analyzed using the distorted wave Born approximation of Levinson and Banerjee. Distorted waves are required to fit the angular correlation function between the de-excitation gamma ray and the inelastically scattered proton from the first 2/ sup +/ state in C/sup 12/ when the incident proton energy is 40 Mev. The azimuthal correlation functions are also best explained using the distorted wave theory. Within the framework of the Levinson-Banerjee theory the A/B ratio shows that the nuclear wavefunctions describing the ground and first excited state of C/ sup 12/ are close to the extreme j-j coupling limit.
