Measurements of the nuclear charge distribution in heavy-ion collisions with Breit-Wheeler process

We report the collision energy dependence of the cross section of dielectrons from the Breit-Wheeler process in heavy-ion collisions computed by the lowest-order QED. It has been demonstrated that the experimental measurements of the Breit-Wheeler process in ultra-relativistic heavy-ion collisions can be used to quantitatively constrain the nuclear charge radius.
