摘要:

不同的手段被用来研究放射性的,外来的离子,17,19 C的光谱。首先,估计已使用壳模型的系统。从这些壳模型研究的信息,然后用于评估截面的散射70 A MeV的17,19 C离子从氢。补充这些研究,多通道代数散射(MCAS)理论的n+16,18 C耦合通道的问题已被用来确定的化合物系统的结构。结果表明,对这些离子所假设的壳模型结构是合理的,所需的有效电荷很少。在离基态几百keV的范围内存在两个激发态的条件对结构模型有一定的限制。其他正宇称态预计在两个原子核的低位光谱。

英文摘要:

Diverse means are used to investigate the spectra of the radioactive, exotic ions, 17,19C. First, estimates have been made using a shell model for the systems. Information from those shell model studies were then used in evaluating cross sections of the scattering of 70A MeV 17,19C ions from hydrogen. Complementing those studies, a multichannel algebraic scattering (MCAS) theory for n+16,18C coupled-channel problems has been used to identify structures of the compound systems. The results show that the shell model structure assumed for these ions is reasonable with little need of effective charges. The conditions that two excited states exist within a few hundred keV of the ground state places some restriction upon the structure models. Other positive parity states are expected in the low-lying spectra of the two nuclei.
