Theoretical study on hard-x-ray spectral redistributions using single or multiple magnetic switching in two-target nuclear forward scattering was conducted. It was found that the system is noncommutative, with magnetic perturbation at the downstream target having a higher impact on spectral intensity enhancement than that at the upstream target.
Hard-x-ray spectral redistributions using single or multiple magnetic switching in two-target nuclear forward scattering is theoretically studied. We show that our system is noncommutative, namely, a mag-netic perturbation at the downstream target leads to a higher spectral intensity enhancement than the spectral boost by a magnetic perturbation at the upstream target. Our scheme not only enhances the spectral intensity to tenfold but also provides a time-delayed magnetic control on the Fano-like spec-trum. The present two-target results pave the way towards a brighter and more flexible x-ray source than the one-target scheme for precision spectroscopy of nuclear resonances utilizing modern synchrotron radiation.
