Indium 115 Spectrum - Gran Sasso Experiment

Post by Steve Dubyk » 22 May 2015, 00:31

After reading what was necessary to detect the In-115 peak at 497 keV, looks like we won't see this one with our equipment! To us, it will be "observationally stable".

"intensive irremovable background"

In our course lab the students do experiments on indium every year, but I never knew it was not quite stable. It is excellent for neutron activation experiments: large cross section and the product In-116 has a suitable half-life of about one hour, decaying with distinctive gammas.
