Models of realistic Reggeons for t=0 high energy scattering

Autor: Kontros, J., Kontros, K., Lengyel, A.

Several Regge-phenomenological models of forward scattering at high energies are considered. It was found that one of them corresponds to the form of finite series in log s with additional terms that represent the exchanges of non-degenerate Regge-tr

Maximum entropy method and oscillations in the diffraction cone

Autor: Dumbrajs, O., Kontros, J., Lengyel, A.

Publikováno v: J.Phys.G26:1321-1326,2000

The maximum entropy method has been applied to investigate the oscillating structure in the pbarp- and pp-elastic scattering differential cross-section at high energy and small momentum transfer. Oscillations satisfying quite realistic reliability cr

Pomeron models and exchange degeneracy of the Regge trajectories

Autor: Kontros, J., Kontros, K., Lengyel, A.

Two models for the Pomeron, supplemented by exchange degenerate sub-leading Regge trajectories, are fitted to the forward scattering data for a number of reactions. By considering new Pomeron models, we extend the recent results of the COMPAS group,

Local nuclear slope and curvature in high energy $pp$ and $\bar pp$ elastic scattering

Autor: Desgrolard, P., Kontros, J., Lengyel, A. I, Martynov, E. S.

Publikováno v: Nuovo Cim. A110 (1997) 615-630

The local nuclear slope $B(s,t) = {d \over d t} (\ln {d\sigma_n (s,t)\over dt})$ is reconstructed from the experimental angular distributions with a procedure that uses overlapping $t$-bins, for an energy that ranges from the ISR to the $S\bar ppS$ a

Electron Impact Excitation and Ionization of Sulfur, Selenium, and Tellurium Vapors

Autor: Shpenik, O. B., Erdevdy, M. M., Markush, P. P., Kontros, J. E., Chernyshova, I. V.

Український фізичний журнал; Том 60 № 3 (2015); 217

Excitation and ionization processes of sulfur, selenium, and tellurium vapors by a low-energy (1–50 eV) electron impact have been investigated. The emission spectra are studied in the wavelength range 200–590 nm. The optical excitation functions
