Differential and partial cross sections of elastic and inelastic positronium-helium-atom scattering
(Amer Physical Soc, 2000-12-01)
Scattering of positronium (Ps) by a helium atom has been investigated in a three-Ps-state coupled-channel model including Ps(1s,2s,2p) states using a recently proposed time-reversal-symmetric regularized electron-exchange ...
Differential and partial cross sections of elastic and inelastic positronium-helium-atom scattering
(2000-12-01)
A three-positronium-state coupled-channel model was utilized to investigate the scattering of positronium (Ps) by a helium atom at low and medium energies. A regularized symmetric nonlocal electron-exchange model potential ...

Mutual friction in helium II: A microscopic approach
(American Institute of Physics, 2009-12)
We develop a microscopic model of mutual friction represented by the dissipative dynamics of a normal fluid flow which interacts with the helical normal modes of vortices comprising a lattice in thermal equilibrium. Such ...
