Abstract:The results of a systematic study performed on Pb-Sn alloys of concentration 65–35% and 94–6% by weight along with spectra from pure Pb and Sn in the wavelength range of 9.8–18 nm are presented. The dynamics of the Nd:YAG laser produced plasma were changed by varying the focused spot size and input energy of the laser pulse; the laser irradiance at the target varied from 7.3 × 109 W cm−2 to 1.2 × 1012 W cm−2. The contributing ion stages and line emission are identified using the steady state collisional radiat… Show more
“…The last three papers describe results obtained with laser-produced plasmas. Scally et al [11] report on the results of a systematic study of the emission between 10 and 18 nm from plasmas produced with Sn, Pb and lead-tin alloys targets, under a variety of laser irradiation conditions and alloy concentrations. The ion stages contributing to the emission are identified through a collisional radiative model and atomic structure codes.…”
