Calculations of pion excess in nuclei
- 1. Department of Physics, University of Illinois at Urbana-Champaign, Urbana, Illinois 61801
Description
The authors construct, in the static potential approximation, the number operator for excess pions present in nuclei due to the pion-exchange forces between nucleons. Expectation values are calculated with use of variational wave functions obtained from a realistic Hamiltonian. Results are presented for systems ranging from the deuteron to nuclear matter: For example 56Fe is estimated to have approx.7 extra pions, over and above the pion clouds associated with the individual nucleons
