Nuclear Reaction Cross-Section Theory

Reviews of Modern Physics, 1960
A summary of compound nucleus processes is given and a method, based on the compound nucleus model, is given for estimating the magnitude and energy dependence of nuclear cross sections. Expressions for the logarithmic derivative were derived, based on the two nuclear potentials: a strong interaction model (real square-well potential) and a square-well

Pion reaction cross sections and nuclear sizes

Nuclear Physics A, 1973
Abstract Measurements have been made of the reaction cross sections of π − and π + mesons for the nuclei C, Ca, Ni, Sn and Pb at beam momenta of 0.71, 0.84, 1.00, 1.36, 1.58 and 2.00 GeV /c . Additionally measurements have been made for Al, 120 Sn, Ho and 208 Pb at momenta of 0.84, 1.00, 1.36 and 1.58 GeV /c .

Cross sections of deuteron induced nuclear reactions on iridium

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2006
Abstract Excitation functions of the reactions natIr(d, xn)188,189,191,193mPt and natIr(d, x)189,190g,192g,194g,194m2Ir were measured up to 40 MeV using the stacked foil technique. No earlier cross sections were found in the literature. The measured experimental data were analyzed and compared to theoretical calculations based on the model code ALICE-

Nuclear reaction cross sections for proton therapy applications

Journal of Radioanalytical and Nuclear Chemistry, 2017
Nuclear reactions of high-energy protons with treatment equipment, air, and patient tissue during proton therapy generate residual radioactivity and secondary particles including protons, deuterons, alphas, and neutrons. The most up-to-date versions of INCL++ (v5.2.9), TALYS (v1.8), EMPIRE (v3.2.2 Malta), and ALICE/ASH were used in this study to ...

Parameter sensitivities in nuclear reaction cross-section calculations

Annals of Nuclear Energy, 2002
Abstract The present work explores the relationships between measured neutron reaction data and the parameters of nuclear models used to calculate comparable results as well as to interpolate and extrapolate into domains where measurements are not feasible.

Effect of Nuclear Deformability on Reaction Cross Sections

Physical Review C, 1970
We have calculated the effect of nuclear deformability on the cross section for interaction of heavy ions with uranium. Static calculations indicate that these effects should be large; dynamic calculations with liquid-drop parameters indicate that they should be smaller, but measurable with currently available heavy ions (argon incident on uranium ...

On resonance phenomena in nuclear reaction cross sections

Journal of Physics G: Nuclear Physics, 1982
The conclusions obtained using the continuum shell model for resonance phenomena are compared with experimental data from the 52Cr+p reaction obtained at energies with and without isobaric analogue resonances. The influence of channel coupling on the result of an autocorrelation analysis is investigated for the 15N+n nuclear reaction cross section ...

Nuclear Radii Extracted from Experimental Reaction Cross Sections

Chinese Physics Letters, 2003
We illustrate typical experimental reaction cross sections sigma(R) which have obtained on RIBLL at Heavy Ion Research Facility of the Institute of Modern Physics (IMP) at Lanzhou. The corresponding nuclear radii are extracted from the measured experimental sigma(R) using the Glauber model. Meanwhile, theoretical nuclear radii are also calculated using

Compound-nuclear reaction cross sections from surrogate measurements

Reviews of Modern Physics, 2012
Nuclear reaction cross sections are important for a variety of applications in the areas of astrophysics, nuclear energy, and national security. When these cross sections cannot be measured directly or predicted reliably, it becomes necessary to develop indirect methods for determining the relevant reaction rates.

Cross Sections of Proton Induced Nuclear Reactions on Iridium

AIP Conference Proceedings, 2005
Excitation functions of the reactions natIr(p,xn)188,189,191Pt and natIr(p,x)186,187,188,189,190,192Ir were measured up to 70 MeV for practical applications. The measured experimental data were compared with the earlier results and analyzed using theoretical calculations based on the model code Alice‐IPPE, The new experimental data show significant ...
