\title{Fully-First-Principles Quantum Calculations of Helium-Broadened
Metal Resonance Lines}

\author{Timothy C.\ Lillestolen and Robert J.\ Hinde}

\date{6 January 2006}

\maketitle

\begin{abstract}

Alkali and alkaline earth atomic resonance lines, broadened by
collisions between the metal atoms and ambient H$_2$ and He, make
substantial contributions to the atmospheric opacity of several
brown dwarfs and other low mass astronomical objects. Analysis of
these collisionally-broadened absorption features can in principle
provide information about the composition and physical conditions of
the atmospheres of these objects.  This has stimulated  both a variety of
studies of the absorption features' line shapes and several attempts
to use model line shapes to fit the observed dwarf spectra.

Here we present fully first-principles quantum calculations of the
He-broadened Na I resonance line, calculations based on high-quality
quantum chemical studies of the Na--He potential energy and
transition dipole moment curves.  We also investigate the
sensitivity of the collisionally-broadened Na I line shape to the
underlying potential and transition moment functions. This makes it
possible to assess the reliability of commonly-used simplifications,
such as the assumption that the transition moment is independent of
the Na--He distance.  If time permits, we will also present some
preliminary work on the He-broadened K I and Ca I resonance lines.
