摘要：

We present expressions which go beyond the usual non-relativistic approximations for the electromagnetic decay widths of vector and pseudoscalar mesons in the quark model. Numerical calculations within typical potential models for heavy quark-antiquark system shows the corrections thus obtained to be substantial. Possible experimental implications for the ψ and Υ{hooked} families are discussed. © 1979.
