通过荷能离子 (包括团簇离子 )辐照聚乙烯首次合成了小于C6 0 的富勒烯———C2 0 和C2 6 分子晶体 .在此基础之上 ,进一步探索其他小富勒烯分子晶体 (如C32 ,C38和C2 4 )存在的确凿证据 .
The fullerenes C2 0 and C2 6, which are smaller than C6 0, were firstly synthesized by irradiating polyethylene with charged ions (including cluster ions) .On the basis of this, we further explored other small fullerene molecular crystals (Such as C32, C38 and C2 4) the existence of conclusive evidence.
