Abstract：
The di-gamma and di-gluon decay widths of P-wave cc mesons are computed in nonrelativistic phenomenological quark-antiquark potential of the type V(r)=－4/3α_s/r+Ar^ν with different choices of ν using spectroscopic parameters. The numerically obtained radial solutions are employed to obtain the di-gamma and di-gluon decay widths. The computed decay widths are consistent with other model predictions as well as with the known experimental values in the range of potential index 0.7≤ν≤1.1.
