Query: Antisymmetrized Molecular Dynamics with Coherent State Pion and Its
  Application to Excited Spectrum of 12C   We have introduced coherent state neutral pion into Antisymmetrized Molecular
Dynamics. With the aid of coherent state technique, it becomes possible to
calculate transition matrix elements of the pion field operator and to study
excited states containing pions. For large pion-nucleon coupling fpiN > 1.6,
pions have a finite expectation value and bring large energy gain in 12C. We
discuss two aspects of pionic effects in spectroscopy; the LS interaction like
effect and the mixing of different nucleon parity states, which would modify
low energy nuclear levels.
