  A number of works point to the presence of narrow emission features at
unusual energies in the X-ray spectra of active galactic nuclei (AGN) or to
potentially low iron abundances as possible evidence for the spallation of
iron. With the imminence of high-resolution calorimeter spectroscopy, the
potential to test spallation models in astrophysical sources will soon be
possible. Previously determined nuclear spallation reactions of Fe are
recalculated making use of improved total inelastic and partial reaction cross
sections that result in different absolute and relative abundances of the main
spallation elements Mn, Cr, V, and Ti. The effects of ionisation and dynamics
near the black hole are examined in simulated spectra with CCD and calorimeter
(i.e. Hitomi) resolution. With high-resolution, differences in relative
abundances and ionisation should be detectable if spallation is originating at
large distances from the black hole (e.g. torus or disc wind) where blurring is
not significant. If spallation were occurring in the inner accretion disc, it
would likely be undetected as blurring effects would cause significant blending
of spectral features.
