Contents of the workshop:
It is getting clear that the the pion should be treated explicitly for
the structure of finite nucleus.  The density dependence of the
effective interaction (G-matrix) is removed when the tensor force (pion
exchange) is removed in the G-matrix calculation.  In this case, we have
to treat the tensor force explicitly for the nuclear structure
calculations.  A new method is proposed in which intrinsic single
particle states are constructed by breaking the parity and the charge
quantum numbers.  The variational wave function is then constructed by
making the projection of the parity and the charge from the total
intrinsic wave function and take variation of the expectation value of
the Hamiltonian with respect to the single particle state.  This
formulation is named as the parity and charge projected Hartree-Fock
method with finite pion mean field.  We discuss the calculational
details of this method and also the calculated results.  In the closed
session, we would like to discuss on the content of the publicaiton.
