determination of 238Pu / 239Pu isotope ratio by alpha Standard applies to plutonium solutions free from 241Am and those containing less than when the aim is to study the fine structure of the plutonium α spectrum.
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. After appropriate weighting and summation the simulated Am-Be source spectrum was obtained.

Secure Login De senaste tweetarna från @alphaspectrumx I picked up a Tek 1401A Spectrum Analyzer at a hamfest recently, and it inspired me to do a video or two. This one presents a generic block diagram and tuto 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. My Spektrum.

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. After appropriate weighting and summation the simulated Am-Be source spectrum was obtained. This spectrum is compared with the spectrum obtained directly from a source and with spectra published by other authors. Author The misidentified -rays are not associated with the decay of 241Am, but rather are prompt -rays from alpha-induced reactions The γ-ray spectrum of 241Am from 80 to 850 keV was studied with measured spectrum is shown in Fig. 1. The lower spectrum was taken from an extremely thin source of 224 Ra which was produced (6) by recoil implantation from alpha-decaying 228 Th nuclei.

The neutron energy spectrum of the JRC 241Am-Li (alpha,n) radionuclide source has been measured at the PTB in Germany using various spectrometry systems, such as Bonner spheres, proton recoil counters and NE213 liquid scintillators.
