文摘In this study, we perform systematic estimations of the radiative decays of the charmed mesons in a modified relativistic quark model. Our estimations indicate that the branching ratios of the processes of D^(0)_(2)(1^(3)P_(2)) →D^(0)(1^(3)S_(1)) γ , D_3^0(1D_3) o D^(0)_(2)(1^(3)P_(2)) γ , D^(0)_(2)(2D_2^) o D_1^(0)(2P_1) γ , D_3^0(2^3D_3) o D^(0)_(2)(2^3P_(2)) γ , and D^(\ast 0)(1^(3)S_(1)) o D^0(1^1S_0) γ are of the order of 10^(-2) , which are sizable to be detected experimentally. Moreover, the branching ratios of some channels, for example, D_1^0(1P_1) o D(1^1S_0)^0 γ , D^0(3^1S_0) o D_1^( 0)(2P^_(1)) γ , and D^0(3^3S_(1)) o D^(0)_(2)(2^3P_(2)) γ , are estimated to be of the order of 10^(-3) , which may be accessible with the accumulation of data in future experiments.
