摘要：

We have measured the pressure broadening and shift of the excitation and emission lines of the 6s2 S-1(0) --> 6s6p P-1(1) transition of Ba atoms implanted in liquid and solid helium at 1.5 K. The observed spectra are quantitatively explained within the adiabatic line-broadening theory by assuming a bubble structure of the trapping sites for the Ba atoms. The evolution of the bubble shape and size in the optical excitation-deexcitation cycle is modeled theoretically.
