摘要：
We calculate partial widths for the decays a(0)(980) --> gamma gamma and f(0)(980) --> gamma gamma under the assumption that a(0)(980) and f(0)(980) are members of the basic 1(3)P(0)cq (q) over bar nonet. The results are in a reasonable agreement with data thus giving an argument: for a q (q) over bar origin of these mesons. We also calculate the yy partial widths for the other scalar mesons, members of the 2(3)P(0)q (q) over bar nonet. (C) 1999 Published bg Elsevier Science B.V. All rights reserved.
