Abstract

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 magnetic 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 spectrum. 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.
