Abstract
Radiative transitions among heavy quarkonium systems are investigated in a general framework of the boosted LS-coupling (BLS) scheme, where mesons are treated in a manifestly covariant way and conserved effecti ve currents are explicitly given. As a result it is shown that our the ory reproduces the qualitative features of experiments remarkably well , giving evidence for the validity of the BLS scheme.
