“…The decreasing trend for deuteron energies greater than 5 MeV on 54,56 Fe isotopes has also been shown in the theoretical estimations of Ref. [11] while for 58 Fe they indicated an increasing trend up to about 9 MeV of the deuteron energy. The reason for the discrepancy is not clear at the moment.…”

“…Recent studies [10,11] have shown that measured differential elastic scattering cross sections of deuterons on medium-mass nuclei were not reproduced by theoretical calculations, especially at backward angles and for bombarding energies below 20 MeV. Using our elastic scatter-ing data, we examined known optical model parameters for deuteron energies below 10 MeV.…”

“…In Ref. [28], the same authors compare their breakup fraction estimates for the proton channel alone (but including elastic breakup) with the preliminary results from this project [13], where the breakup cross section that is lost in the present estimates due to the forward-angle dip was not subtracted. If that cross section is added to the present estimates for all channels, the points in the lower panel of Fig.…”

Background: Projectile breakup can make a large contribution to reactions induced by projectiles with mass numbers 2, 3, and 4, yet there is no global model for it and no clear agreement on the details of the reaction mechanism.Purpose: This project aims to develop a phenomenological model for light-projectile breakup that can guide the development of detailed theories and provide a useful tool for applied calculations.Method: An extensive database of double-differential cross sections for the breakup of deuterons, 3 He ions, and α particles was assembled from the literature and analyzed in a consistent way.Results: Global systematics for the centroid energies, peak widths, and angular distributions of the breakup peaks have been extracted from the data. The dominant mechanism appears to be absorptive breakup, where the unobserved projectile fragment fuses with the target nucleus during the initial interaction. The global target-mass-number and incident-energy dependences of the absorptive breakup cross section have also been determined, along with channel-specific normalization constants. Conclusions:Results from the model generally agree with the original data after subtraction of a reasonable underlying continuum. Absorptive breakup can account for as much as 50 to 60% of the total reaction cross section.

“…Avrigeanu et al (2014) performed cross-section measurements by irradiating thin foils of natural iron using the stacked foil technique with a 19.74 MeV deuteron beam and found that the 54 Fe(d,n) 55 Co excitation function reaches a maximum of ~ 158 mb at 6.71 MeV. The predicted thick target production yield from this excitation function integrated over the energy on the impinging particles available from a GE PETtrace cyclotron, 8.2 MeV, as they are slowed down in the target material is 23.2 MBq/μA h. Likewise, from the 58 Ni(p,α) excitation functions that were measured by Khandaker et al (2011) we can predict a thick target yield with our 16 MeV proton beam of 15.6 MBq/μAh.…”

This work presents the production with a cyclotron of the positron emitter 55Co via the 54Fe(d,n) and 58Ni(p,α) reactions and the Auger electron emitter 58mCo via the 57Fe(d,n) reaction after high current (40 μA p and 60 μA d) irradiation on electroplated targets. High specific activity radionuclides (up to 55.6 GBq/μmol 55Co and 31.8 GBq/μmol 58mCo) with high radionuclidic purity (99.995% 55Co from 54Fe, 98.8% 55Co from 58Ni, and 98.7% 58mCo from 57Fe at end of bombardment, EoB), in high activity concentration (final separated radionuclide in < 0.6 mL) and with almost quantitative overall activity separation yield (> 92%) were obtained after processing of the irradiated targets with novel radiochemical separation methods based on HCl dissolution and the resin N,N,N′,N′-tetrakis-2-ethylhexyldiglycolamide (DGA, branched). One hour long irradiations using 38–65, 110–214 and 59–78 mg of enriched 54Fe (99.93%), 58Ni (99.48%) and 57Fe (95.06%), respectively, electroplated over a 1.0 cm2 surface, yielded 582 ± 66 MBq 55Co, 372 ± 14 MBq 55Co and 810 ± 186 MBq 58mCo, respectively, decay corrected to EoB. The separation methods allow for the recovery of the costly enriched target materials, which were reconstituted into metallic targets after novel electroplating methods, with an overall recycling efficiency of 93 ± 4% for iron. The produced radionuclides were used to radiolabel the angiogenesis marker antibody TRC105 conjugated to the chelator NOTA as a demonstration of their quality.
