ORNL-CCIP-91-28 UTK-91-10 TWO-PHOTON COUPLINGS OF QUARKONIA WITH ARBITRARY ANGULAR MOMENTAt T.Barnes Physics Division and Center for Computationally Intensive Physics Oak Ridge National Laboratory, Oak Ridge, TN 37831-6373 and Department of Physics, University of Tennessee, Knoxville, TN 37996-1501 ABSTRACT The observation of a large y7 width for the 'D2 qq state ir2(1670) suggests that the -yy couplings of many orbitally-excited light qq states may be experimentally accessible. In this talk we present yy helicity amplitudes for qq states with general angular momenta If, and 't, and note some relations and selection rules that may be useful in spectroscopic classification of orbital excitations.
