We calculated radiative decay widths of possible radiative transitions
between S-wave charmed baryons in naive static quark model and in non
-relativistic quark potential model, The results obtained in these two
approaches are in a fair agreement. We predict the following life tim
e for Omega(c)(+) and Xi(c)' baryons: tau(Omega(c)') approximate to 10
(-18) s, tau(Xi(c)') approximate to 10(-19) s.
