    "abstract": "Differential cross sections for electron collisions with the O$_2$ molecule\nin its ground ${X}^{3}\\Sigma_g^-$ state, as well as excited ${a}^{1}\\Delta_g$\nand ${b}^{1}\\Sigma_g^+$ states are calculated. As previously, the fixed-bond\nR-matrix method based on state-averaged complete active space SCF orbitals is\nemployed. In additions to elastic scattering of electron with the O$_2$\n${X}^{3}\\Sigma_g^-$, ${a}^{1}\\Delta_g$ and ${b}^{1}\\Sigma_g^+$ states, electron\nimpact excitation from the ${X}^{3}\\Sigma_g^-$ state to the ${a}^{1}\\Delta_g$\nand ${b}^{1}\\Sigma_g^+$ states as well as \u00276 eV states\u0027 of\n${c}^{1}\\Sigma_u^{-}$, ${A\u0027}^{3}\\Delta_u$ and ${A}^{3}\\Sigma_u^{+}$ states is\nstudied. Differential cross sections for excitation to the \u00276 eV states\u0027 have\nnot been calculated previously. Electron impact excitation to the\n${b}^{1}\\Sigma_g^+$ state from the metastable ${a}^{1}\\Delta_g$ state is also\nstudied. For electron impact excitation from the O$_2$ ${X}^{3}\\Sigma_g^-$\nstate to the ${b}^{1}\\Sigma_g^+$ state, our results agree better with the\nexperimental measurements than previous theoretical calculations. Our cross\nsections show angular behaviour similar to the experimental ones for\ntransitions from the ${X}^{3}\\Sigma_g^-$ state to the \u00276 eV states\u0027, although\nthe calculated cross sections are up to a factor two larger at large scattering\nangles. For the excitation from the ${a}^{1}\\Delta_g$ state to the\n${b}^{1}\\Sigma_g^+$ state, our results marginally agree with the experimental\ndata except for the forward scattering direction.",
