Özet
Using data samples collected with the BESIII detector operating at the BEPCII storage ring at center-of- mass energies from 4.178 to 4.600 GeV, we study the process e(+)e(-) pi X-0(3872)gamma and search for Z(c)(4020)(0) -> X(3872)gamma. We find no significant signal and set upper limits on sigma(e(+)e(-) -> pi X-0(3872)gamma) . B(X(3872) -> pi(+)pi(-)/J/psi) and sigma(e(+)e(-) -> pi(0)Z(c)(4020)(0)). B(Z(c)(4020)(0) -> X(3872)gamma) . B(X(3872) -> pi(+)pi(-) J/psi) for each energy point at 90% confidence level, which is of the order of several tenths pb.
