abstract = {We observe the radiative decay $D^{*}_{s0}(2317)^{+} \to
D_{s}^{*+} γ$ for the first time, with a significance
exceeding $10$ standard deviations. The signal is found in
the continuum $e^+ e^- \to c\bar{c}$ process with the
combined data samples of 980.4~$\rm fb^{-1}$ and 427.9~$\rm
fb^{-1}$ collected by the Belle and Belle~II detectors
operating at the KEKB and SuperKEKB asymmetric-energy
$e^+e^-$ colliders, respectively. The branching fraction
ratio ${\cal B}(D^{*}_{s0}(2317)^{+} \to D_{s}^{*+}
γ)/{\cal B}(D^{*}_{s0}(2317)^{+} \to D_{s}^{+} π^{0})$ is
measured to be $[7.14 \pm 0.70({\rm stat.}) \pm 0.23({\rm
syst.})]\\%$. This result provides significant new
experimental input for the determination of the quark
structure of the $D^{*}_{s0}(2317)^{+}$, which remains
unknown.},
