In this.article, we inves.igate the nonrelativis.ic quantum motion of a charged particle within a rotating frame, taking into ac.ount the Aharonov–Bohm(AB) effect and a uniform magnetic field. our analy.is.entails.the derivation of the equation of motion and the corres.onding radial equation to des.ribe the s.1}tem. s.lving the res.lting radial equation enables.us.to determine the eigenvalues.and eigenfunctions. providing a clear expres.ion for the energy.levels. Furthermore,our numerical analy.is.highlights.the s.bs.antial influence of rotation on both energy.levels.and optical properties. s.ecifically. we evaluate the photoionization c.os.-s.ction with and without the effects.of rotation. To elucidate the impact of rotation on the photoionization proces. of the s.1}tem, we pres.nt graphics.that offer an appealing vis.alization of the intrins.c nature of the phy.ics.involved.
