New Ion Beam Handbook:  "Pitfalls in IBA"

Chris Jeynes and Nuno Barradas would like to invite the IBA community to look 
at the current draft of the new chapter "Pitfalls in Ion Beam Analysis".  We 
would 
welcome comments from the community aimed at improving this work.

In particular we would invite colleagues to draw our attention to errors and
significant omissions.  We will also be glad to consider suggestions for 
further 
literature references.  

We append below the Table of Contents of the draft chapter:  the full text 
can be downloaded from  http://www.surreyibc.ac.uk/index.php?target=13:79
