摘要: Abstract 39 K NMR signals from the orthorombic and tetrahedral sites are detected at high T, in 3 C 60 . However below 210K a new line appears. Its characteristics nearly identical to those found for extra 87 Rb observed 400K , which suggests that low T structural electronic properties of superconducting A compounds quite similar. The variations shifts have been studied cubic phase down state. They surprisingly be dominated by variation orbital contributions.
