摘要：

The integral properties of channel interference in resonant X-ray scattering (RXS) are formally investigated. The qualitative difference between vibrational and electronic state lifetime interference is elucidated. It is shown that the integral interference term in the RXS cross section summed over all intermediate and final states is exactly equal to zero. A few experimental cases are given as illustration. As a result of numerical simulations it is found that the integral interference term is also close to zero if only certain finite sets of intermediate and final states are taken into account.
