The low-energy electron spectrum from the alpha-decay of 241Am has been analysed in the region of 2.5 - 22.5 keV at the 20 eV instrumental resolution using a combined electrostatic spectrometer and 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. 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 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. Abstract The neutron energy spectrum of a 241 Am-Be (_,n) source was measured by means of a 3 He spectrometer in the energy range from 100 keV to 11 MeV. The spectrometer consisted of two semiconductor detectors with a proportional counter arranged between them to measure the energy loss of the 3 He (n,p) 3 H reaction particles in the 3 He gas. The Alpha Decay of 241Am C. M. LEDERER, J. K. POGGENBURG t, F. ASARO, J. O. RASMUSSEN and I. PERLMAN Department of Chemistry and Lawrence Radiation Laboratory, University of California, Berkeley, California ** Received 8 March 1966 Abstract: The ~,-ray spectrum of ~41Am from 80 to 850 keV was studied with a high resolution semi- conductor T-ray spectrometer; ~-7" and s-electron-coincidence spectra were studied with semi- conductor and scintillation detectors. The alpha-spectrum tailing function used for the determination of 238 Pu/ 239 Pu and 241 Am/ 239 Pu in plutonium isotopic mixtures is described.

1973-10-01 · From the 241Am/B and 241Am/F spectra (Figs. 2 and 3), it can be clearly seen that the spectrometer is capable of operation down to at least 1 MeV. Detail in the 2"Am/F spectrum indicates that the instrument has an energy resolution (dE/E) of better than 10 per cent at 2 MeV. The alpha-particle spectra of Am241 and Cm242 was studied in detail utilizing a 75-cm radius of curvature 60° symmetrical electromagnetic analyzer with photographic plate detection. The radioactive sources containing up to 3 μg/cm2 of active atoms in the case of Am241 were prepared by vacuum sublimation. The average geometry of the spectrograph is Your account at your fingertips.

Abstract: The pure and unperturbed (ideal, at birth) spectra of 241AmLi (alpha,n)10B sources were determined using Monte Carlo simulations, along with the neutron spectrum measured outside a source’s encapsulation. Various parameters that affect photon and neutron yields and energy distributions were investigated.
