The 14N(α, n) and 16O(d, n) excitation functions

Evidence for boson-mode excitations in the16O(α,n) and20Ne(α,n) excitation functions

“…Ref. [5]) is most suitable to obtain integrated cross sections. The final nuclei of the (c~, n) reactions decay by t+ emission.…”

“…To check this model the (~, n) process is particularly suitable because it permits the measurement of absolute cross sections integrated over angles and excited states of the residual nuclei. Since few such integrated cross sections of (~, n) type are known [4,5], excitation functions have been measured for the reactions 160 (e, n) and 2~ n) for the first time. The comparison with other related excitation functions leads to a new interpretation of intermediate structures.…”

Neutron production in (α,n) reactions

“…Rows 'EMPIRE3.2.3 + Exp' include results obtained using cross-sections from measurements where available, replaced by EMPIRE3.2.3 calculations at higher energies. Given a large spread of experimental data for cross-sections, only one measurement was used for each isotope and these measurements were taken from: [36] for 19 F, [40] for 13 C, [52] for 14 N, [46] for 27 Al, [53] for 17 O and 18 O, [54] for 28 Si, [47] 29 Si and 30 Si, [55] for 50 Cr, [56] for 54 Fe, [57] for 55 Mn, [49] for 60 data is very large (larger than for calculated cross-sections in realistic models) and there is no obvious choice of the data set to use. Measurements of the cross-sections are usually limited to the total cross-sections and do not provide transition probabilities to various excited states (not to high excited states anyway) so the use of a model is unavoidable to obtain the correct neutron spectrum.…”

Effect of partition coefficient, permeability surface product, and radioisotope on the signal-to-noise ratio in PET functional brain mapping: a computer simulation

“…This reaction has a huge cross section (D 500 mb at 5 MeV). Using the cross-section data from Gruhle et al [1972] and the stopping power equation [Turner, 1978], we calculated the thick target yield to be 232 mCi/µA at 11 MeV. In 1987, Mulholland et al reported the production of greater than a Curie of F-17 using this reaction.…”
