Abstract

A resonance in the ⁵²Cr(p, γ)⁵³Mn reaction has been investigated as a probe for the quantitative determination of chromium depth distributions. The relevant nuclear parameters of this resonance were measured to be: resonance energy, E_p = (1005.2±0.2) keV, total width Γ < 100 eV, and resonance strength, (2J+1)Γ_pΓ_γ/Γ = (0.89±0.11) eV. As an example of the use of the nuclear resonance technique, the chromium profile of an electroplated chrome black solar absorber surface has been studied and the results are presented.

It corresponds to isobaric analogue resonances (IARs) caused by the population of so-called isobaric analogue states in the compound nucleus. IARs usually have a decay scheme different from the background resonances, and unique primary gamma rays from the decay of IARs can be used for resonance profiling [13–14]. For a long time the SigmaCalc calculator was hosted at the IAEA Nuclear Data Section server.
The extension of the cross-section evaluation procedure to PIGE data was investigated and the first results are reported. Two different cases were studied: the gamma emission accompanying inelastic scattering of protons, and the (p,γ)-reaction. The corresponding theoretical calculations were performed in the framework of R-matrix and DWBA for the (p,p′γ) reaction on ²³Na, and using statistical model for the proton radiative capture by ⁵²Cr. The possibility of achieving a close fit to the experimental data is demonstrated.
Oxide scale depth profiling of lanthanum-deposited AISI-304: An ion beam analysis
1998, Nuclear Instruments and Methods in Physics Research, Section B: Beam Interactions with Materials and Atoms
A detailed study of the composition and evolution with time of oxide scales formed onto lanthanum-coated AISI-304 stainless steel specimens by means of the PYROSOL deposition method at 1173 K in air, has been done with the help of ion beam analysis techniques such as Rutherford backscattering spectrometry (RBS) and nuclear reaction analysis (NRA) of Cr and Mn. Complementary data have been obtained by means of other analytical techniques such as Scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX) and thermogravimetric measurements (TG), proving the effectiveness of the deposition method for enhancing the refractory behaviour.
Prompt ion beam analysis by pulsed beams
1988, Nuclear Inst. and Methods in Physics Research, B
A 1 ns duration, 6 MHz repetition rate pulsed and bunched beam has been used to improve the sensitivity of particle-induced gamma ray emission analytical techniques by appropriate time-gating of the detector. The detection system was gated to be receptive to pulses only during a period, typically < 8 ns, appropriate to the time of arrival of true target gamma ray signals generated by the pulsed beam. Besides the true peak, secondary peaks resulting from beam interaction with specific beam line apertures and components, and a continuous background were seen. The degree of improvement is dependent on many parameters, inter alia the bombarding beam energy and species, the target matrix, the beam line geometry and characteristic gamma ray transition energies being measured. Improvement factors typically between 2 and 5 have been achieved. The technique is particularly relevant for higher-energy proton- or deuteron-induced reaction analyses where neutron production and beam-induced radioactivity leads to high detector backgrounds.
Determination of oxygen in thin films with the 16O(3He, pγ)18F reaction
1980, Nuclear Instruments and Methods
The cross sections for the production of 937, 1040 and 1080 keV γ-rays deexciting the first three levels in ¹⁸F have been measured for the ¹⁶O(³He, pγ)¹⁸F reaction. In the bombarding energy range from 2.6 MeV to 4.0 MeV, the summed cross section for the production of these three γ-rays rises from 10 mb to 90 mb. This reaction has been applied to the measurement of the oxygen content in chrome black solar absorber surfaces. The known photothermal properties of these samples were correlated with the oxygen and chromium concentrations and were found to be optimum for an average composition near CrO_0.45.
