What the Third Rank Tensor Analyzing Powers Can Tell Us

The odd rank analyzing powers T-T(10) and T-T(30) for C-12((7)(Li) over right arrow,(7)(Li) over right arrow)C-12 and C-12((7)(Li) over right arrow, alpha)N-15 have been measured with high precision for a (7)(Li) over right arrow bombarding energy of 34 MeV. The angular distributions of the T-T(10) and T-T(30) data are strongly correlated, marking the first experimental evidence of a relationship between analyzing powers of different rank. The ratio of T-T(30) to T-T(10) obeys limits derived from the assumptions that the reaction is both peripheral and well localized in the reaction plane, allowing, for the first time, a third rank analyzing power to contribute to our understanding of Li-7.
