Absolute absorption coefficients for the Sr resonance line at 4607 AA perturbed by He, Ne and Kr below 700 Torr have been measured at about 1000K in the spectral range of about 1 to 100 cm-1 on both sides of the line centre. The profile of Sr-Kr shows a strong asymmetry and has a red satellite at about 35 cm-1 from the line centre. The profiles of Sr-He and Sr-Ne show, on the other hand, rather symmetric features and have a power dependence of approximately -2 on the separation from the line centre. An empirical interaction potential has been deduced from the red satellite of Sr-Kr using the unified Franck-Condon (UFC) method of Szudy and Baylis (1975). It has a well of depth 40 cm-1 at an interatomic distance of 6.6 AA. Optical cross sections have been deduced from the profiles of Sr-He and Sr-Ne using a classical impact analysis. The results are 117 and 135*10-16 cm2 respectively. Finally the measured absorption profiles are compared with a recent experiment on collisionally redistributed radiation.
