skbeam.core.constants.xrf.emission_line_search

skbeam.core.constants.xrf.emission_line_search(line_e, delta_e, incident_energy, element_list=None)

Find elements which have an emission line near an energy

This function returns a dict keyed on element type of all elements that have an emission line with in delta_e of line_e at the given x-ray energy.

Parameters

line_efloat

energy value to search for in KeV

delta_efloat

difference compared to energy in KeV

incident_energyfloat

incident x-ray energy in KeV

element_listlist, optional

List of elements to restrict search to. If no list is present, search on all elements. Element abbreviations can be any mix of upper and lower case, e.g., Hg, hG, hg, HG

Returns

lines_dictdict

element and associate emission lines
