Abstract
A resonance-dominance picture of reactions is shown to lead to threshold enhancements in angle-integrated cross sections under a random-sign or oscillating-sign condition for coupling constants. Formulas are derived for threshold-enhanced reaction rates. Application is made to several reactions and compared to measured cross sections.
