Fast-ion-beam laser and laser-rf double-resonance measurements of hyperfine structure in 83Kr II.

Abstract

We have applied the methods of fast-ion-beam laser spectroscopy (FIBLAS) and laser-rf double resonance to study the 4${p}^{4}$${(\mathrm{}}^{3}$P)4d ${\mathrm{}}^{4}$${D}_{7/2}$\ensuremath{\rightarrow}4${p}^{4}$${(\mathrm{}}^{3}$P)5p ${\mathrm{}}^{4}$${D}_{7/2}^{o}$ transition at 642.018 nm in $^{83}\phantom{\rule{0ex}{0ex}}\mathrm{i}\mathrm{i}$. The effective hyperfine constants of the 4d ${\mathrm{}}^{4}$${D}_{7/2}$ state were measured by radiofrequency magnetic resonance, with the results (in MHz) A=-43.5132(3), B=-294.921(5), and C=-0.0030(6). The FIBLAS results for the 5p ${\mathrm{}}^{4}$${D}_{7/2}^{o}$ effective hyperfine constants are (in MHz) A'=-145.29(7) and B'=536(2). .AE
