Low-energy Antiproton Interaction with Helium
arXiv:nucl-th/9705007 · doi:10.1103/PhysRevA.56.3553
Abstract
An ab initio potential for the interaction of the neutral helium atom with antiprotons and protons is calculated using the Born-Oppenheimer approximation. Using this potential, the annihilation cross section for antiprotons in the energy range 0.01 microvolt to 1 eV is calculated.
