Abstract
angular correlations of the form have been measured as a function of energy for the two decays . and . The results of the angular correlations are considered in a model independent analysis, along with a comparison to model dependent wave function calculations. The coefficient is a kinematic term that depends on , where is the center of mass velocity of the particle. A detailed comparison between the experimental results and the theoretical prediction for shows that the measured kinematic term is (10-15)% smaller than the prediction. The coefficients arise from induced weak currents. Utilizing the -parity properties of these currents, we discuss the results corresponding to . The second order energy dependence in is found to be negligible. Assuming no second order energy dependence, the experimental result is , where and are the weak magnetism and second class currents, and is the Gamow-Teller current. The experimental result for determines the first class induced tensor current , and the second forbidden axial currents and . The interpretation of is complicated since wave function predictions indicate that all three currents should contribute significantly to .
