Summary

It is proposed to measure polarizations of the recoil neutron in π+ photoproduction inorder to detect a possibleT violation in the electromagnetic interaction of hadrons. Several possibilities of introducingT-violating terms in the photoproduction current are discussed.

Riassunto

Si propone di misurare le polarizzazioni del neutrone di rinculo nella fotoproduzione di π+ allo scopo di rivelare una possibile violazione diT nell'interazione elettromagnetica degli hadroni. Si discutono parecchie possibilità di introdurre termini che violanoT nella corrente della fotoproduzione.
