Talk:Relativistic similarity parameter

Is expression for normalized vector potential correct? In the page, it is ${a_{0}=eA/m_{e}c^{2}}$, but it seems incorrect because ${eA}$ have dimension of momentum but $m_{e}c^{2}$ have dimension of energy. I think this should be ${a_{0}=eA/m_{e}c}$. Am I right? YoshiGosu (talk) 11:46, 31 May 2017 (UTC)
