The nonleptonic weak decay processes $\hat{I}{\text{c◯}}_c\to \hat{I}\text{c◯}\ddot{I}{€}^{+}/\hat{I}\text{c◯}(1P)\ddot{I}{€}^{+}/\hat{I}\text{c◯}(1D)\ddot{I}{€}^{+}/\hat{I}\text{c◯}(2S)\ddot{I}{€}^{+}$ are studied using the constituent quark model. The branching fraction of $\hat{I}{\text{c◯}}_c\to \hat{I}\text{c◯}\ddot{I}{€}^{+}$ i…
