Pauli equation in spaces of constant curvature and extended Nikiforov-Uvarov method

Abdaljalel E. Alizzi, Zurab K. Silagadze

We apply the extended Nikiforov-Uvarov method to the non-relativistic limit of the Dirac equation with a Coulomb potential in spaces of constant curvature. In this case, the radial…

Measurement of the neutron timelike electric and magnetic form factors ratio at the VEPP-2000 $e^{+} e^{-}$ collider

M. N. Achasov, A. E. Alizzi, A. Yu. Barnyakov +38

In the experiment to study the e+e->n+anti n process at the VEPP-2000 $e^{+} e^{-}$ collider, the ratio |GE|/|GM| of the neutron timelike electric and magnetic form factors has been mea…

Measurement of the $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ cross section in the energy region from 0.56 to 1.1 GeV with the SND detector

SND Collaboration, M. N. Achasov, A. E. Alizzi +44

The precise measurement of the $e^{+} e^{-} \to I ¨ ^{+} I ¨ ^{-} I ¨ ^{0}$ cross section is performed in the center-of-mass energy range $E = 560$ --1100 MeV using a data sample of 66 pb $^{- 1}$ collect…

Astrophysical positronium and Dicke superradiance

Abdaljalel E. Alizzi, Zurab K. Silagadze

Dicke superradiance is a fascinating phenomenon in which a large number of atoms cooperate to produce a brief and very intense burst of spontaneous emission. This phenomenon has be…

Measurement of the $e^{+} e^{-} \to I^\cdot I^^{3}$ cross section near the $I ¨ (1020)$ resonance with the SND detector

SND Collaboration, M. N. Achasov, A. E. Alizzi +38

In the experiment with the SND detector at the VEPP-2000 $e^{+} e^{-}$ collider, the $e^{+} e^{-} \to I^\cdot I^^{3}$ cross section is measured in the energy range $E = 980 - 1060$ MeV. The measurement…

Elementary atoms in spaces of constant curvature by the Nikiforov-Uvarov method

Abdaljalel E. Alizzi, Alina E. Sagaydak, Zurab K. Silagadze

The Nikiforov-Uvarov method is a simple, yet elegant and powerful method for solving second-order differential equations of generalized hypergeometric type. In the past, it has bee…
