    "abstract": "We have introduced coherent state neutral pion into Antisymmetrized Molecular\nDynamics. With the aid of coherent state technique, it becomes possible to\ncalculate transition matrix elements of the pion field operator and to study\nexcited states containing pions. For large pion-nucleon coupling fpiN \u003e 1.6,\npions have a finite expectation value and bring large energy gain in 12C. We\ndiscuss two aspects of pionic effects in spectroscopy; the LS interaction like\neffect and the mixing of different nucleon parity states, which would modify\nlow energy nuclear levels.",
