This app has been designed by RaySpec as a valuable tool for x-ray spectroscopy measurements.

It permits a user to specify a transition energy value in keV and automatically determines and displays the elements and 'lines' closest to this value.

It also allows the user to select an element and displays the x-ray transition energies for this element.

Values are based on experimental values. Where experimental values are not available the database uses theoretically derived values.
The app also includes a database with general properties for each element.
