241Am, 210Po, 244Cm (substitute alternate sources with electrons on one end of the spectrum and 200 MeV heavy Simple Alpha Spectrum and Energy.

The primary alpha particle emitted by 241Am has an energy of approximately 5.486 MeV (see Chart of the Nuclides). 7. Normalize your pulser using the 241Am peak and following the procedure outlined in Lab 1. 241 Am---Alpha spectroscopy Spectroscopy Introduction The purpose of this experiment is to study the detection of alpha particle radiation from Am source and the attenuation of this radiation during Am-241 is primarily an alpha emitter, but also emits some gamma rays. It poses a more significant risk if ingested (swallowed) or inhaled.

Calculations with the MCNP transport code have been used to explain some of the features seen in the spectrum. © 2019 Charter Communications. All rights reserved; Advertise with Us; Your Privacy Rights; Web Privacy Policy; California Consumer Privacy Rights; California A radioactive Li(alpha, n) neutron source is unique because its spectrum with an average energy of about 0.5 MeV bridges the energy gap between photoneutron sources and the commonly used Be(alpha, n) sources. Radioactive neutron sources find wide application for the calibration of instruments and for this purpose an accurate knowledge of the neutron spectrum emitted is nearly always essential. OSTI.GOV Thesis/Dissertation: Study of partial wave branching in the alpha decay of 241 Am, 253 Es, and 255 Fm ‪Rutherford Scattering‬ - PhET Interactive Simulations The spectrum shows fairly broad maxima at 3.5 and 5 MeV and extends up to 11.5 MeV. This is similar to the published spectra of Po-210Be(alpha, neutron) sources. The partial neutron spectrum from the production of the 4.43 MeV state of C-12 was studied separately by a time of flight method; it is in fair agreement with calculated spectra.
