# Keyword:SPEK

SPEK

This keyword causes the calculation of an approximate γ spectrum for nuclides in the decay library which have no spectral data. These nuclides are flagged by an ‘&’ in the inventory output and in the output of library data produced in a run with the keyword PRINTLIB.

Example usage:

< -- Control phase -- >

SPEK
