Abstract

Absolute cross sections for the reactions $^{54} Cr (p, γ)^{55} Mn and^{54} Cr (p, n)^{54} Mn$ are presented for effective bombarding energies E_p from 0.830 to 3.606 MeV. A substantial cusp is observed in the $^{54} Cr (p, γ)^{55} Mn$ excitation function. The data are compared with the predictions of global Hauser-Feshbach models in order to evaluate their applicability to nucleosynthesis calculations.

Accelerated radiation damage test facility using a 5 MV tandem ion accelerator
2015, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
We have developed a new irradiation facility that allows to perform accelerated damage tests of nuclear reactor materials at temperatures up to 400 °C using the intense proton (<100 μA) and heavy ion (≈10 μA) beams produced by a 5 MV tandem ion accelerator. The dedicated beam line for radiation damage studies comprises: (1) beam diagnosis and focusing optical components, (2) a scanning and slit system that allows uniform irradiation of a sample area of 0.5–6 cm², and (3) a sample stage designed to be able to monitor in-situ the sample temperature, current deposited on the sample, and the gamma spectrum of potential radio-active nuclides produced during the sample irradiation. The beam line capabilities have been tested by irradiating a 20Cr–25Ni–Nb stabilised stainless steel with a 3 MeV proton beam to a dose level of 3 dpa. The irradiation temperature was 356 °C, with a maximum range in temperature values of ±6 °C within the first 24 h of continuous irradiation. The sample stage is connected to ground through an electrometer to measure accurately the charge deposited on the sample. The charge can be integrated in hardware during irradiation, and this methodology removes uncertainties due to fluctuations in beam current. The measured gamma spectrum allowed the identification of the main radioactive nuclides produced during the proton bombardment from the lifetimes and gamma emissions. This dedicated radiation damage beam line is hosted by the Dalton Cumbrian Facility of the University of Manchester.
Cross-sections for (p,x) reactions on natural chromium for the production of 52,52m,54 Mn radioisotopes
2015, Applied Radiation and Isotopes
Citation Excerpt :
This work focused primarily on measurements for the production of 52Mn, but also for 52mMn and 54Mn as radiocontaminants. Only a few data sets are currently available with points at proton beam energy (Ep) ≤14 MeV for the natCr(p,x) reactions that produce 52,52mMn (Barrandon et al., 1975; Buchholz et al., 2013; West Jr et al., 1987), and there are only data sets from enriched targets available for 54Mn at these low energies (Gusev et al., 1990; Johnson et al., 1960; Kailas et al., 1975; Levkovskij, 1991; Skakun et al., 1986; Zyskind et al., 1978). In this work, we contribute new experimental cross-section data for each of these (p,x) reactions that produce 52,52m,54Mn from bombardment of natural chromium with protons at low-energies.
The production of positron-emitting isotopes of manganese is potentially important for developing contrast agents for dual-modality positron emission tomography and magnetic resonance (PET/MR) imaging, as well as for in vivo imaging of the biodistribution and toxicity of manganese. The decay properties of ⁵²Mn make it an excellent candidate for these applications, and it can easily be produced by bombardment of a chromium target with protons or deuterons from a low-energy biomedical cyclotron. Several parameters that are essential to this mode of production—target thickness, beam energy, beam current, and bombardment time—depend heavily on the availability of reliable, reproducible cross-section data. This work contributes to the routine production of ^52gMn for biomedical research by contributing experimental cross-sections for natural chromium (^natCr) targets for the ^natCr(p,x)^52gMn reaction, as well as for the production of the radiocontaminants ^52m,54Mn.
Cross sections and thermonuclear reaction rates for 51(α, n)54Mn and 51(α, p)54Cr
1993, Nuclear Physics, Section A
The cross sections of⁵¹V(α, n)⁵⁴Mn and ⁵¹V(α, p)⁵⁴Cr have been measured in the bombarding-energy ranges of 2.00–9.49 MeV and 5.755–9.590 MeV, respectively. The cross sections, together with cross sections of ⁵⁴Cr(p, γ)⁵⁵Mn and ⁵⁴Cr(p, n)⁵⁴Mn taken from the literature, have been compared with the results of statistical-model calculations. Thermonuclear reaction rates at temperatures appropriate to silicon burning in massive stars and supernovae have been calculated for both reactions.
Charged particle reaction cross sections and nucleosynthesis
1982, Physics Reports
The role of proton and α-particle induced reactions in carbon, neon, oxygen and silicon burning in massive stars is surveyed. The problems associated with determining thermonuclear reaction rates for reactions with widely spaced resonances and with closely spaced or overlapping resonances are discussed and the associated experimental approaches are reviewed. Experimental techniques which have been used in the measurement of reaction cross sections are discussed and their strengths and weaknesses are identified. Recent developments in attempts to establish reliable statistical-model codes for calculation of reaction cross sections are presented and discussed. Finally, the results of experimental tests of statistical model codes are summarised and evaluated.
Resonances in coupled channels in nuclear and particle physics
1982, Physics Reports
Starting from first principles this report gives account of the important latest developments on resonances in coupled channels in nuclear and hadronic physics. It also gives many new results which have remained hitherto unpublished. All types of poles of the S matrix are considered in coupled-channel problems, on all Riemann sheets. This review includes the classification of poles, their manifestation in the S matrix and cross sections, the dynamics of coupled channels, and the motion of poles when the channel coupling is changing. The case of channels with short-range plus long-range potentials is treated in detail. The special case of resonance plus particle channels is considered and exemplified by the A₁ and Q resonances. Many numerical examples and fits to experimental data are provided.
