This is the continuation of research proposal XRF-18910 titled «A High Resolution Spectrometer for RRS Spectroscopy. Stage 1. Typifying Standard Spectra for Qualitative Analysis in Low Resolution ». In this proposal, it is expected to finish the full commissioning of the x-ray spectrometer. with this new spectrometer, we will study the RRS process when the incident energy is below the L absorption edges (LMRRS), which has never been done before due to the lack of such a spectrometer in a synchrotron radiation facility. We are expecting that these will be the most important results for the PhD thesis of Lic. José Ignacio Robledo, whom is finishing his PhD on March 2019. During the first requested shifts, it is expected to finish the full commissioning of the x-ray spectrometer, which will allow further measurements. With the increase in energy resolution that will be obtained, the methodology we have standardized [1] may reveal information in the fine structure of the RRS peak that may clarify the nature of these oscillations, and allow a better comprehension of this phenomenon.
