Abstract
We conducted experimental and theoretical studies of chiral condensate in the nuclear medium through precision spectroscopy of pionic Sn atoms and subsequent analyses. The chiral condensate at similar to 60% of the nuclear saturation density is found to be reduced by 23 +/- 2% compared to that in the vacuum
