Pressure broadening and shift of D1 line of Ag by He, Ar and N2

We have studied experimentally pressure broadening and shift of Ag D1 line caused by He, Ar and N2 buffer gases. The measurements were done in a heat-pipe type absorption cell at a temperature of ~1000 K and gas pressures up to 1000 torr. The measured values for pressure broadening and shift (in MHz/Torr) are as follows: Ag-He 5.8(1), +1.16(2); Ag-Ar 5.2(2), -2.28(4); Ag-N2 5.2(1), -2.52(7). The "+" and "-" signs indicate the direction for the shifts to the blue and red side of the spectrum, respectively.
