The far-wing photoabsorption and photoemission spectra of the RbAr and lines provoked by collisions with argon atoms have been determined by adopting a full quantum-mechanical approaches. The calculations have been performed for temperatures ranging from 500 to 3000 K, using two different sets of ab initio potential data points. The effect of temperature and of interatomic potentials on the broadening profiles is then analyzed. The results show that only the free-free transitions are dominant and they revealed the existence of blue satellite features at approximately 740 nm and 750 nm depending on the potential set used. The general shapes of the present simulated spectra are similar to those already measured by many other authors.
