The data of energy levels and electric dipole transitions of 1s22s22p2 ground configuration and 1s22s2p3 excited configuration in carbon-like ions with Z=10, 14, 32, 36, 50

Baed on MCDHF method and GRASP program, the energy structure and E1 transition parameters of 1s22s22p2 and 1s22s2p3 configurations for carbon-like isoelectronic sequences (Z=10,14,32,36,50) were calculated and collected. 2.The dataset consists of five parts, namely the relative error between the excitation energy of 1s22s22p2 and 1s22s2p3 configurations in Ne V and Si IX ions with VV correlation, VV+CV correlation, and VV+CV+CC correlation and NIST data (Figure 1 in the text), energies of atomic states for 1s22s22p2 and 1s22s2p3 configurations in Carbon-like ions (Z=10,14,32,36,50) within AS2~AS7 active spaces (Table 1 in the text), the excitation energy of 1s22s22p2 and 1s22s2p3 configurations for carbon-like ions (Z=10,14,32,36,50) (Table 2 in the text), the mixing coefficient and lifetime of 1s22s22p2 and 1s22s2p3 configurations for carbon-like ions (Z=10,14,32,36,50) (Table 3 in the text), and the wavelength, transition rate, weighted oscillator strength and line strength of E1 transition between 1s22s2p3-1s22s22p2 for carbon-like ions (Z=10,14,32,36,50).
