The ${a}_{0}^{0}(980)$-${f}_{0}(980)$ mixing intensity has been predicted to be in the range of 0.01 to 0.2 by various theoretical models, but it lacks firm experimental observation. We examine the possibility of extracting the ${a}_{0}^{0}(980)$-${f}_{0}(980)$ mixing from the $J/\ensuremath{\psi}\ensuremath{\rightarrow}\ensuremath{\phi}{f}_{0}(980)\ensuremath{\rightarrow}\ensuremath{\phi}{a}_{0}^{0}(980)$ reaction at the upgraded Beijing electron positron collider with the BESIII detector. …
