The neutron energy spectrum of an 241Am-Li radionuclide source has been measured in a low scatter room at the National Physical Laboratory, using a variety of spectrometers namely: a Bonner sphere set, a 3He ionisation chamber, and a set of hydrogen recoil proportional counters. Calculations with the MCNP transport code have been used to explain some of the features seen in the spectrum.

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.

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. The alpha-ratio of 238 Pu to 239+240 Pu is determined from sources purified by anion exchange. The alpha-ratio of 238 Pu + 241 Am to 239+240 Pu is then Collect the 241Am alpha spectrum until the peak height is at least 1000 counts. The primary alpha particle emitted by 241Am has an energy of approximately 5.486 MeV (see Chart of the Nuclides). 7.

Similar examples are given for each of the spectral A new search for production of correlated pairs in the decay of (241)Am has been carried out deep underground at the Gran Sasso National Laboratory of the IN Abstract. We have developed MICROMEGAS (MICRO MEsh GASeous) detectors for detecting a particles emitted from an 241 Am standard source. The voltage applied to the ionization region of the detector is optimized for stable operation at room temperature and atmospheric pressure.
