## This file is a very simple database. (1) Blank lines or lines
## beginning with a hash (#) are ignored. (2) Entries contain three
## fields, separated by a vertical bar (|). The first field is the
## common name of the material. The second field is the chemical
## formula, written according to the rules of Chemistry::Formula. The
## third field is the density of the material.
##
## The materials chosen in this file are materials of interest to the
## synchrotron scientist.
##
## Many of these materials were swiped from a list provided by Erik
## Gullikson at Berkeley's center for X-Ray Optics.
