Plotting these rates as a function of δ detuning [Fig. 3(b)], we see that S→ is flat in the region of δ = 0, whereas for larger values of δ it increases exponentially until our measurement is bandwidth limited. The rate of the S → (1,1) process is expected to be constant since it depends only on th ...

Rutherford backscattering spectrometry
Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions (typically protons or alpha particles) impinging on a sample.
