摘要：
The possibility of controlling the X-ray spontaneous emission of atoms embedded in a 1-dimensional photonic bandgap structure by the so-called Purcell effect, is studied. Calculations of the spontaneously emitted power are presented from Fermi’s golden rule in the framework of the Wigner-time approach extended to absorbing media. Numerical simulations are compared to experimental results for the case of the K emission from silicon atoms excited by electrons within a Mo/Si multilayer Bragg reflector. The inhibition or enhancement of X-ray emission from such structures appear to be feasible.
