  "abstract": "<p>Using data samples collected with the BESIII detector at the BEPCII collider at six center-of-mass energies between 4.008 and 4.600\u2009GeV, we observe the processes e+e\u2212\u2192\u03d5\u03d5\u03c9 and e+e\u2212\u2192\u03d5\u03d5\u03d5 . The Born cross sections are measured and the ratio of the cross sections \u03c3(e+e\u2212\u2192\u03d5\u03d5\u03c9)/\u03c3(e+e\u2212\u2192\u03d5\u03d5\u03d5) is estimated to be 1.75\u00b10.22\u00b10.19 averaged over six energy points, where the first uncertainty is statistical and the second is systematic. The results represent first measurements of these interactions.</p>",
