In this.article, we inves.igate the nonrelativis.ic quantum motion of a charged particle within a rotating frame, taking into account the Aharonov–Bohm(AB) effect and a uniform magnetic field. Our analys.s.entails.the derivation of the equation of motion and the corres.onding radial equation to des.ribe the s.s.em. 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 analys.s.highlights.the s.bs.antial influence of rotation on both energy levels.and optical properties. s.ecifically, we evaluate the photoionization cros.-s.ction with and without the effects.of rotation. To elucidate the impact of rotation on the photoionization proces. of the s.s.em, we pres.nt graphics.that offer an appealing vis.alization of the intrins.c nature of the phys.cs.involved.
