我们研究了富中子氧同位素20O的ELab(7Li)=44 MeV布居态的14C(7Li，p)多核子转移反应。这些实验是在慕尼黑串列加速器上使用高分辨率Q3D磁谱仪进行的，总能量分辨率为45keV。激发能高达20 MeV的态--在分析中确定了65个态，其中42个是新的。旋转带是根据基本的本征反射-不对称团簇和长分子结构提出的(称为奇偶双重带)。在高激发能下，对于一些很窄的态，建议采用矩形扁平结构。
We have studied the multi-nucleon transfer reaction14C(7Li,p) atELab(7Li) = 44 MeV populating states of the neutron-rich oxygen isotope20O . The experiments have been performed at the Munich Tandem accelerator using the high-resolution Q3D magnetic spectrometer, with an overall energy resolution of 45keV. States were populated up to 20MeV excitation energy --65 states have been identified in the analysis, among which 42 are new. Rotational bands are proposed in terms of underlying intrinsic reflection-asymmetric cluster and prolate molecular structures (namelyas parity doublet bands. A rectangular oblate structure is suggested for some very narrow states at high excitation energies.
