Photon Stimulated Desorption of MgS as a Potential Source of Sulfur in Mercury's Exosphere

<p>Experimental data for x-ray photoelectron spectroscopy (XPS) and resonance enhanced multiphoton ionization (REMPI) characterization of the surface of magnesium sulfide (MgS) exposed to 193 nm UV photons. These data accompany the manuscript &quot;Photon Stimulated Desorption of MgS as a Potential Source of Sulfur in Mercury&rsquo;s Exosphere&quot; &#39;submitted in April 2020 to the Journal of Geophysical Research - Planets. The &#39;Mg-1s&#39; and &#39;S-2p&#39; data were used to make the XPS image (Figure 1). The &#39;power&#39; data were used to make the signal intensity vs. power images (Figures 2 and 3). The &#39;delay&#39; data were used to fit Maxwellian velocity distributions, and the fits are included (Figure 4).&nbsp; The &#39;MC&#39; data were the output results of the Monte Carlo model used to determined the density of sulfur as a function of altitude above Mercury (Figure 6).</p>
