惰性气体对钠共振谱线的影响增宽和位移已经用改进的仪器和考虑到不对称性的数据处理方法重新确定。增加的宽度，位移和不对称性与重惰性气体的注意，是一个D2到D1的宽度比大于1的氦和氖，但小于1的氩，氪和氙。与不同的出版计算的比较表明，无论是与一个完整的量子或半经典的影响增宽理论的帕斯卡尔-范德普朗克潜力的宽度占。另一方面，Nikitin-Roueff势在这种情况下不起作用。可用的计算的转变是不太令人满意的，没有预测所观察到的不对称性。
The impact broadening and shift of the sodium resonance lines by noble gases have been redetermined with improved instrumentation and data reduction allowing for asymmetries. An increase of width, shift and asymmetry with the heavy noble gases is noted, as is a D2 to D1 width ratio greater than one for helium and neon, but less than one for argon, krypton and xenon. Comparisons are drawn with different published calculations to show that the widths are accounted for by the Pascale-Vandeplanque potential whether with a fully quantal or a semiclassical impact broadening theory. On the other hand, the Nikitin-Roueff potential does not work well in this case. Available calculations of the shift are less satisfactory and no predictions of the observed asymmetries have been made.
