THE EFFECT OF POSITRONIUM FORMATION IN E(+)-LI AND E(+)-NA SCATTERING
(Elsevier B.V., 2014)
Ps-H scattering using the three-state positronium close-coupling approximation
(Iop Publishing Ltd, 2014)
Positron annihilation in triphenylphosphine oxide complexes: Positronium inhibition mechanism involving excitation of charge transfer states
(Elsevier Science BvAmsterdamHolanda, 2008)
Positronium impact excitation of hydrogen molecule to B-1 Sigma(+)(u) and b(3)Sigma(+)(u) states
(Iop Publishing Ltd, 1998-04-14)
Calculation for the electronic excitation of the ground state of H-2 to B (1) Sigma(u)(+) and b(3) Sigma(u)(+) states by positronium- (Ps) atom impact has been carried out using the first Born approximation considering ...
Scattering of positronium by H, He, Ne, and Ar
(Elsevier B.V., 2000-01-28)
The low-energy scattering of the ortho-positronium (Ps) by H, He, Ne, and Ar atoms has been investigated in the coupled-channel framework by using a recently proposed time-reversal symmetric non-local electron-exchange ...
Positronium-hydrogen atom elastic scattering at medium energies
(Iop Publishing Ltd, 2000-10-28)
We study the elastic scattering of positronium atoms by hydrogen atoms at medium energies using partial-wave Born-Oppenheimer (BO) exchange amplitudes and report accurate BO cross sections in the energy range 0 to 60 eV. ...
Positronium scattering by atoms and molecules at low energies
(Elsevier B.V., 2002-05-01)
The recent theoretical and experimental activities in positronium (Ps) scattering by atoms and molecules are reviewed with special emphasis at low energies. We critically compare the results of different groups - theoretical ...
Positronium scattering by a hydrogen molecule including exchange
(Iop Publishing Ltd, 1998-09-28)
We perform a three-positronium (Ps) state [Ps(ls,2s,2p)] coupled-channel calculation of Ps-H-2 scattering including the effect of electron exchange. At medium energies, higher excitations and ionization of Ps are treated ...
Positronium atom scattering by H-2 in a coupled-channel framework
(Iop Publishing Ltd, 2000-04-28)
The scattering of ortho-positronium (Ps) by H-2 has been investigated using a three-Ps-state (Ps(1s,2s, 2p)H-2(X (1)Sigma(g)(+))) coupled-channel model and using the Born approximation for higher excitations and ionization ...
