127SN c An unknown excited state with half-life of 3.1 |ms {I9} has been
127SN2c proposed by 1980De35 from |b|g(t) results for 715|g and 1094|g,
127SN3c which have equal delayed intensities.
127SN c The decay scheme is proposed at first by 2000Pi03. The detail of decay
127SN2c scheme including the 16.52 keV isomeric transition and 5 other |g-rays
127SN3c is reported by 2004Ga24.
