We used an 241Am source, which emits a 59.5-keV gamma ray2, to fluoresce the elements. With this gamma ray we were able to fluoresce the K electrons of the

Jul 16, 2020 Accuracy of the 241Am Capture Cross-section was launched to review all for 241Am reactivity worth in a well-thermalised neutron spectrum .

Many workers have determined 241Am/Be spectra to have 3 and 5-0 MeV peaks of equal intensity, (7,8) but as can be seen from Fig. 4, our sources show spectra with the 4-8-5-0 MeV peak much less pronounced 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.

to safeguard efficient use of spectrum, or to fulfil a general interest objective in (SIMS), suffers from isobaric interferences (238U/238Pu,241Am/241 Pu).

The source is an alpha emitter, and in the decay process it also kicks out a gamma at 59.6KeV. 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 241Am–Li neutron spectrum measured with the 3He spectrometer and unfolded with the iteration code. The data have been normalised to unit total fluence between 50 and 1500keV. The 241Am–Li neutron spectrum measured with the SP2 proton recoil counters, down-scatter corrected and unfolded with the HEPRO package.

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.

The spectrum from 241Am/F shows fine structure not previously reported eleswhere. We report on an investigation of the fast-neutron spectrum emitted by 241Am/9Be. Well-understood shielding, coincidence, and time-of-flight measurement techniques are employed to produce a continuous, polychromatic, energy-tagged neutron beam.

The difference of integrated fluence in the 2–11 MeV energy range between the ISO distribution and the new measurements performed with the IRSN detector system is 2% (Table 2). The I perform an activation study to estimate the residual dose rate from the activation drum. I use 241Am-Be with the energy sampled of the respective spectrum (I set the distribution to be isotropic in the BEAM card). Again, I have neutron emission rate (n/s) obtained using the relation from literature.
