dc.description.abstractIn a previous laserspectroscopic study of the $A^{2}\Pi \leftarrow X^{2}\Sigma$ transition of NaAr five vibrational levels $v = 0\ldots4$ of the $X^{2}\Sigma$ state have been $observed^{a}$. Recently, we have performed an improved high-resolution investigation of this transition yielding experimental information on two more vibrational levels $v = 5$ and $6. 135$ absorption lines have been observed starting from $v = 5$ and leading to $v' = 6\ldots 8$ of $A^{2}\Pi$. Only a few lines connecting $v = 6$ with $v' = 5\ldots 7$ could be detected. Therefore the assignment of rotational quantum numbers is very tentative in this case. Our preliminary results for the spectroscopic parameters of these levels are (in units of $cm^{-1}$) $$\begin{array}{cccc} & T_{v}-T_{o}& 10^{2}B_{v}&10^{5}D_{v}\\ v=5&34.22(10)&1.72(2)&2.3(2)\\v=6&35.09(20)&0.52(4)&---\end{array}$$ The $X^{2}\Sigma$ interaction potential has been determined in form of an analytical HFD function using our standard method of $approach^{b}$. In addition, the spectral distribution of the fluorescence $A\leftarrow X$ has been recorded showing the well-known reflection structure and allowing a determination of the repulsive part of the $X^{2}\Sigma$ potential.en_US
