# Xray::Absorption::None(3pm)

Fallback methods for Xray::Absorption

## NAME

Xray::Absorption::None - Fallback methods for Xray::Absorption

## SYNOPSIS

```
   use Xray::Absorption;
   Xray::Absorption -> load("none");
```

See the documentation for Xray::Absorption for details.

## DESCRIPTION

This module is inherited by the Xray::Absorption module and provides access to the data contained in the 1999 Elam tables of line and edge energies by inheriting that module.  The cross\_section method is overloaded and always returns 0 regardless of what mode is selected.

This rather strange functionality is a crude hack to benefit the ATP mechanism used by Atoms and related programs.

## EDGE AND LINE ENERGIES

See Xray::Absorption::Elam.
