Ratios involving on-resonance measurements of the three-fold and five-fold
correlation cross sections for which the dependence on some of the unknown
spectroscopic data is eliminated are considered. Closed form expressions are
derived for the statistical distributions of these ratios. Implications for
bounds on the variance of matrix elements of time reversal non-invariant
nucleon-nucleon interactions are considered within a Bayesian framework and the
competitiveness with bounds from other experiments is evaluated. The prospects
for null five-fold correlation measurements improving by an order of magnitude
or more upon the current bound on a parity-conserving T-odd interaction are
good.Comment: 14 pages, to be published in Physics Letters
