We calculate the cross sections for the reactions, νe+3 H → e-+3 He , and νμ+3 H → μ-+3 He from threshold to 1 GeV. We obtain typical contributions of the individual form factors as well as the interference terms to the cross sections. We find that the cross sections for these processes are extremely large for a number of reasons, making them worthy of consideration for possible experiments. We also obtain a typical differential cross section and note the presence of sharp minima for high neutrino energies.

Cross sections for the exclusive reactions, [Formula: see text], and [Formula: see text] are obtained from threshold to 1 GeV. We find the contributions of the individual form factors as well as all interference terms to the cross sections of both of these reactions. We find that the cross sections for these processes are relatively large making them possible candidates for experiments. We also obtain differential cross sections for suitable energies for these reactions and note the presence of sharp minima which might be observable with a well peaked neutrino flux. We also estimate the cross sections for the inclusive reactions [Formula: see text] and [Formula: see text] from threshold to a few hundred MeV.

The Cross

The differential cross section for the Rhodium and Tantalum has been calculated by using the Cross Section Calculations (CSC) in range of energy(1keV-1MeV) . This calculations based on the programming of the Klein-Nashina and Rayleigh Equations. Atomic form factors as well as the coherent functions in Fortran90 language Machine proved very fast an accurate results and the possibility of application of such model to obtain the total coefficient for any elements or compounds.

The Cross

The two-pion production in pp-collisions has been investigated in exclusive measurements from threshold up to Tp = 1.36 GeV . Total and differential cross sections have been obtained for the channels pnπ+π0, ppπ+π-, ppπ0π0 and also nnπ+π+. For intermediate incident energies Tp > 1 GeV , i.e. in the region, which is beyond the Roper excitation but at the onset of ΔΔ excitation the total ppπ0π0 cross section falls behind theoretical predictions by as much as an order of magnitude near 1.2 GeV, whereas the nnπ+π+ cross section is a factor of five larger than predicted. A model-unconstrained isospin decompostion of the cross section points to a significant contribution of an isospin 3/2 resonance other than the Δ(1232). As a possible candidate the Δ(1600) is discussed.

Scattering Cross

Differential cross sections for elastic scattering and ionization in positron–argon collisions as a function of energy (40–150 eV) are reported at 60°. Of particular interest is the energy range 55–60 eV, where earlier measurements by the Detroit group found a drop in the elastic-scattering cross section of a factor of 2. This structure has been tentatively attributed to a cross channel-coupling effect with an open inelastic-scattering channel, most likely ionization. Our results indicate that ionization remains an important channel over the same energy range and only begins to decrease at an energy above 60 eV.

The World

The application of standard-less PIGE requires the a priori knowledge of the differential cross section of the reaction used for the quantification of each detected light element. Towards this end, a lot of datasets have been published the last few years from several laboratories around the world. The discrepancies found can be resolved by applying a rigorous benchmarking procedure through the measurement of thick target yields. Such a procedure is proposed in the present paper and is applied in the case of the 19F(p,p’γ)19F reaction.

Characteristic Features

We have investigated the form factors of the π and K mesons within the framework of the statistical model. Our results reveal several well-spaced minima and maxima for different values of Q2, the square of the momentum transfer. The characteristic features of the elastic differential cross section, dσ/dt, for π±P and K±P scattering data are well reproduced, as a consequence.

Triple Differential Cross Section

The dependence of the bremsstrahlung perpendicular and parallel triple differential cross sections and the linear polarization on the angles and energies of the incident and scattered electron and of the emitted gamma-ray has been studied in the high-energy small-angle hypothesis. The expression used for the bremsstrahlung triple differential cross section is valid in the Born approximation and for an unscreened Coulomb potential of the nucleus.

The Cross

The differential cross sections for 4.3 MeV neutrons elastically scattered from natural samples of U, Bi, and Pb have been measured at laboratory angles of 5, 10, and 15°. In the case of uranium, the data are consistent with calculations based on the nuclear optical model and known electromagnetic interactions. Less satisfactory agreement to the data is obtained in the cross section measurements for lead and bismuth.

Differential cross sections of the 7Li(p,p0)7Li, 7Li(p,p1)7Li, 7Li(p,α0)4He, 19F(p,p0), 19F(p,α0)16O and 19F(p,α1,2)16O reactions have been determined for proton energies Elab=1500-7000 keV, using a variable energy step and for detection angles between 140-170 degrees in steps of 10 degrees. To validate the obtained results, benchmarking measurements were performed, using thick and mirror-polished BaF2 and LiF targets. The experimental data are compared to data from literature, when available, and similarities and discrepancies are presented and analyzed.
