dc.description.abstractUsing data samples collected with the BESIII detector operating at the BEPCII collider at 17 center-of-mass energies from 3.810 to 4.600 GeV, we perform a study of e⁺e⁻ → ηJ/ψ and π⁰J/ψ The Born cross sections of these two processes are measured at each center-of-mass energy. The measured energy-dependent Born cross section for e⁺e⁻ → ηJ/ψ shows an enhancement around 4.2 GeV. The measurement is compatible with an earlier measurement by Belle.en_US
