Using data samples with an integrated luminosity of $4.5 {fb}^{- 1}$ collected by the BESIII detector at center-of-mass energies ranging from 4.66 GeV to 4.95 GeV, we study the processes of $e^{+} e^{-} \to ω X (3872)$ and $e^{+} e^{-} \to γ X (3872)$ . With the $e^{+} e^{-} \to ω X (3872)$ process, the branching fraction ratio $R \equiv \frac{B (X (3872) \to γ J / ψ)}{B (X (3872) \to π^{+} π^{-} J / ψ)}$ is measured to be $0.38 \pm 0.2 0_{stat} \pm 0.0 1_{syst}$ ( $R < 0.83$ at 90% confidence level). In addition, we measure the ratio of the average cross section of $e^{+} e^{-} \to ω X (3872)$ to $e^{+} e^{-} \to ω χ_{c 1} (ω χ_{c 2})$ to be $σ_{ω X (3872)} / σ_{ω χ_{c 1}} (σ_{ω X (3872)} / σ_{ω χ_{c 2}}) = 5.2 \pm {1.0}_{stat} \pm {1.9}_{syst} (5.5 \pm {1.1}_{stat} \pm {2.4}_{syst})$ . Finally, we search for the process of $e^{+} e^{-} \to γ X (3872)$ , and no obvious signal is observed. The upper limit on the ratio of the average cross section of $e^{+} e^{-} \to γ X (3872)$ to $e^{+} e^{-} \to ω X (3872)$ is set as $σ_{γ X (3872)} / σ_{ω X (3872)} < 0.23$ at 90% confidence level.
