“…24 The full-width-at-half-maximum (FWHM) and frequency shift of each Gaussian distribution are the same, and the peak frequency of the Ti Two different peaks at relative frequencies of approximately -4.5 and 4.5 GHz, corresponding to 394.86474 and 394.86942 nm, respectively, are observed due to the under-cosine shape 25 of the spatial distribution of the differential sputtering yield. 26 The density of sputtered titanium atoms in the ground state is relatively low around the central axis. As a result, two peaks appear at the relative frequencies of -4.5 and 4.5 GHz.…”
