HOWEVER, THIS IS NOT THE CASE FOR THE DIFFERENTIAL CROSS SECTIONS, SO THAT A DETAILED-BALANCE TEST FOR TIME REVERSIBILITY BECOMES POSSIBLE,IN PRINCIPLE, IN THE REGION OF ISOLATED RESONANCES. WE DESCRIBE THE FIRST SUCH EXPERIMENTAL TEST OF DETAILED BALANCE, THE REACTION STUDIED BEING 27AL+P --> <-- 24MG+ALPHA, TAKING PLACE THROUGH THE ISOLATED J-PI=2+ RESONANCE AT EXC-ENGY=12.901 MEV IN 28SI.
