Data publikacji:: 2019
Wydawca:: Przedsiębiorstwo Wydawnictw Naukowych Darwin / Scientific Publishing House DARWIN
Tematy:: coupled states
deuteron
parameterization
shifts
variable phase approach
Opis:: Variable phase approach is viewed for two-channel scattering. The search of the scattering phases and mixing parameter for coupled states 3S1–3D1 using Stapp parameterization is carried out. The nucleon-nucleon potential in the coordinate representation is used for numerical calculations. The influence of the choice of a numerical method (method Euler and methods Runge-Kutta) on the calculations of scattering phases and the mixing parameter is taken into account.

Tematy:: analytic form

density distribution
deuteron
transition density
wave function
Opis:: Values of density distribution and transition density are calculated using the obtained coefficients of four deuteron wave function for analytical forms in coordinate representation for Argonne v18 potential. Calculations of these values can serve for an assessment of a correctness and accuracy of choice of an analytical form at concrete approximation of radial deuteron wave function. Also these calculations help to evaluate information on such characteristics of a deuteron as a charge form factor, tensor polarization and momentum distribution.

electron-deuteron scattering
Opis:: The components for differential cross-section was considered with taking into account the polarization effects in elastic electron-deuteron scattering. These characteristics are analyzed for angle of electron scattering θ = 70º and different momentums. The angular-momentum dependence of values components for differential cross-section have been evaluated in 3D format. The wave function of the deuteron in the coordinate representation for the Reid93 potential was applied to numerical calculations.

Tytuł:: Analytical forms of the deuteron wave function in coordinate space and deuteron form factors
Autorzy:: Zhaba, V. I.
Powiązania:: https://bibliotekanauki.pl/articles/1066297.pdf
Data publikacji:: 2019
Wydawca:: Przedsiębiorstwo Wydawnictw Naukowych Darwin / Scientific Publishing House DARWIN
Tematy:: deuteron
form factor
polarization observables
position of the zero
wave function
Opis:: Charge GC, quadrupole GQ and magnetic GM deuteron form factor were calculated by analytic forms of the deuteron wave function in the coordinate space for nucleon-nucleon potentials NijmI, NijmII, Nijm93, Reid93 and Argonne v18. Theoretical calculations are compared with the experimental data from the leading collaborations (Bates, BLAST, Bonn, JLab, Mainz, Naval Research Lab, NIKHEF, Orsay, Saclay, SLAC, Stanford, VEPP3, VEPP4) and reviews (Abbott, Boden, Garcon, Karpius). The obtained position of the zero for the deuteron form factors for these five potentials was compared with the values for other potential models and experimental values. Further use of form factors for obtaining polarization observables is discussed.

Tematy:: amplitude function

variable phase approach
wave function
Opis:: Numerical calculations of the values of phase, amplitude and wave functions for the nucleon-nucleon potential Argonne v18 are carried out using the variable phase approach. Peculiarities of the behavior of these functions are described for coordinates up to 7 fm and with energies of interaction Еlab = 1; 50; 100; 150; 250; 350 MeV. 1S0-, 1P1-, 3P0-, 3P1-, 1D2-, 3D2-, 1F3-, 3F3-, 1G4-, 3G4- states for the np- system are considered. The obtained graphic materials for the indicated functions can help to give a better and more complete quantum mechanical representation of the scattering phase and scattering amplitudes for the neuron-proton scattering, as well as better understand and supplement the data for the problem of scalar amplitude and the full cross-section of the nucleon-nucleon scattering.

Opis:: Within the framework of the study of radiative corrections to the polarization observed in elastic ed- scattering in leptonic variables have been calculated the Born values of vector , and tensor , , asymmetries. The deuteron wave functions in coordinate representation for eight nucleon-nucleon potentials (Nijm1, Nijm2, Nijm93, Reid93, Argonne v18, OBEPC, MT and Paris) have been used for numerical calculations of vector and tensor asymmetries. The angular-momentum dependence of values vector and tensor asymmetries have been also evaluated in 3D format for Reid93 potentials.
