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. I picked up a Tek 1401A Spectrum Analyzer at a hamfest recently, and it inspired me to do a video or two.

Because of its long half-life, 237Np is less hazardous than Alpha and conversion electron spectroscopy of 238,239Pu and 241Am and alpha-conversion electron coincidence measurements Figure 1. Measured (dots) and fitted (lines) alpha spectrum of the 243,241Am material, with interference peaks from 238Pu and tailing from other nuclides at higher energy (bottom). Residuals to the fit (top) © As a clear demonstration of Q spectroscopy, the 241Am alpha source enclosed by a thin gold foil was measured below 100 mK. Its resulting energy spectrum has two dominant peaks with 10 keV FWHM. solutions from whkh 241Am and 237U have been removed. If too much 241Am is present, its 60-keV gamma ray overwhelms all other peaks in the region.
