Abstract: (APS)
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 Fe56 is estimated to have ∼7 extra pions, over and above the pion clouds associated with the individual nucleons.
