1. Cross Sections Listing – cross_sections.xml

1.1. <directory> Element

The <directory> element specifies a root directory to which the path for all files listed in a <library> Element are given relative to. This element has no attributes or sub-elements; the directory should be given within the text node. For example,

<directory>/opt/data/cross_sections/</directory>

1.2. <library> Element

The <library> element indicates where an HDF5 cross section file is located, whether it contains incident neutron or thermal scattering data, and what materials are listed within. It has the following attributes:

materials:

A space-separated list of nuclides or thermal scattering tables. For example,

<library materials="U234 U235 U238" />
<library materials="c_H_in_H2O c_D_in_G2O" />

Often, just a single nuclide or thermal scattering table is contained in a given file.

path:

Path to the HDF5 file. If the <directory> Element is specified, the path is relative to the directory given. Otherwise, it is relative to the directory containing the cross_sections.xml file.

type:

The type of data contained in the file, either ‘neutron’ or ‘thermal’.
