论文摘要
理论上研究了磁扰动的两个目标核向前散射中的X射线频谱。我们表明，通过核靶中磁场的单个或多个转换，可以实现不同的硬X射线光谱重新分布。我们的方案可以生成X射线光谱线，其强度增强和光谱宽度的宽度是核自然线宽的四倍。目前的结果为使用现代同步加速器辐射的核共振精确光谱铺平了朝着更明亮，更灵活的X射线源的道路。
Controlling and narrowing x-ray frequency spectra in magnetically perturbed two-target nuclear forward scattering is theoretically studied. We show that different hard-x-ray spectral redistributions can be achieved by single or multiple switching of magnetic field in nuclear targets. Our scheme can generate x-ray spectral lines with tenfold intensity enhancement and spectral width narrower than four times the nuclear natural linewidth. The present results pave the way towards a brighter and flexible x-ray source for precision spectroscopy of nuclear resonances using modern synchrotron radiation.
