The following spectrum of 241Am, was submitted by Peter Daley, recorded with a GS-1100A and a 2" Alpha Spectra NaI detector. Excellent resolution and a very typical 241Am shape. Recognising isotopes by the shape of their spectra is an art and takes practice, which is why we are building this database of spectra. A thick Be target was irradiated with a 5-48 MeV alpha-beam. Neutron spectra were taken with a stilbene spectrometer at 15 degree intervals.
