\section{Landau theory}\label{sec:phys332-1}
The Landau probability distribution may be written in 
terms of the universal Landau function \cite{bib-LAND}.
\subsection{Restrictions}
The Landau formalism makes two restrictive assumptions:
\begin{enumerate}
\item The typical energy loss is small.
\item The typical energy loss in the absorber should be 
  large (see section \ref{urban}).
\end{enumerate}
\section{Urb\'an model}\label{urban}
The following values are obtained:

100  & 27.59   & &  100  & 32.00
