 THE EXISTENCE OF TWO CLOSELY SPACED RESONANCES SEPARATED BY DELTA-EXC
 =2.09+-0.04 KEV. THE SIMILAR BRANCHING RATIOS OBSERVED FOR THE GAMMA-
 RAY DECAYS OF THE TWO RESONANCES SUGGESTED THE POSSIBILITY THAT THESE
  WERE THE TWO MEMBERS OF THE ISOSPIN-MIXED J-PI=3- DOUBLET. THIS WAS
 CONFIRMED BY FURTHER EXPERIMENTS UTILIZING THE 14N(ALPHA,GAMMA)18F AN
 D 4HE(14N,ALPHA)14N REACTIONS. THIS DOUBLET CAN BE DESCRIBED WITH THE
 COMPLELE MIXING OF T=0 AND T=1 STATES.
