Abstract
A search for the production of a bound trineutron state has been performed using the reaction He-3(pi(-),pi(+))nnn at incident pion energies of 65, 75 , and 120 MeV. No evidence for the existence of the (3)n was found, and an upper limit for the production cross section of approximately 30 nb/sr (2 s igma confidence level) was obtained.
