Atomic core polarization effects in large-l circular orbitals of hadronic helium atoms

摘要

A theoretical consideration is presented concerning the atomic core polarization effect on the E1 transitions of large-l circular orbitals in hadronic helium atoms, e(sup -)X(sup -)He(sup ++), where the e(sup -) occupies the 1s orbital and the negative hadron (X(sup -)) occupies a large-l circular orbital. The first-order mixing of the 2p electron configuration due to the repulsive e(sup -)-X(sup -) interaction gives rise to a substantial suppression ((approx) 1/3) of the E1 transitions, compared with a single-particle estimate, since the slowly-moving particle, X(sup -), polarizes the electron cloud in the opposite direction.
