60Fe production from core-collapse supernovae is predicted to follow
the spatial distribution of 26Al sources, if supernovae produce essentially
all of 26Al in the galaxy. We use the map of 26Al sources
derived from COMPTEL measurements to constrain such correlated
60Fe emission. With more observations and improved background-handling
methods we are able to show that the theoretical prediction under above
assumption of a flux ratio in the radioactivity lines from 60Fe and 26Al
of ~ 16% appears too high. The implications of this finding with respect
to 26Al and 60Fe production sources will be discussed.
