The calculations indicate that: (i) Taking the observed states $\\Lambda_c(2595)^+$ and $\\Lambda_c(2625)^+$ as the $1P$-wave $\\lambda$-modes states $\\Lambda_c|J^P=1/2^-,1\\rangle_{\\lambda}$ and $\\Lambda_c|J^P=3/2^-,1\\rangle_{\\lambda}$, respectively, we can reproduce the experimental data well in theory.
