I totally agree with @DarioP. People many times accelerate ions with singly/doubly charged states to several 100s of MeV in cyclotrons and no appreciable radiation is detected. If the electrons radiate as if they are free then the energy loss will be significant and that will alter their orbits, but it is not observed. For example uranium atom is ...

I have the feeling that the (partially stripped) ion should be considered as a single particle. The residual electrons should influence the emitted radiation just by altering the charge state of the ion, therefore the $C_\gamma$ parameter which enters in the calculation of the total emitted power and power spectrum. The external bending field should be ...

If iron is dissolved in water (polar liquid), it will be in the form of ions. If we apply uniform magnetic field these ions will gyrate around this magnetic field and will do nothing but if we apply a non uniform magnetic field and the non uniformity is perpendicular to the direction of magnetic lines the ions will slowly drift from high field region to low ...

A magnetic field won't do anything, but if you apply an electric field you can electrolyse the iron salt and produce metallic iron. There are some other more involved ways it could be done. For example zeolites will selectively absorb some metal ions. If you choose the correct zeolite you could remove all the iron. Though arguably this is just a form of ...
