利用达姆施塔特GSI的LAND-FRS装置，通过库仑激发研究了富中子~（34），~（35）Al同位素。不变质量分析方法被用来重建衰变前原子核的激发能。通过比较实验CD截面与直接破碎模型计算的p3/2轨道中子的结果，发现34 Al（g.s）- νp3/2是35 Al的基态构型。但34 Al库仑破碎后的γ谱表明，34 Al的基态组态是复杂的。©作者所有，由EDP Sciences出版，2014年。
Neutron-rich 34,35Al isotopes have been studied through Coulomb excitation using LAND-FRS setup at GSI, Darmstadt. The method of invariant mass analysis has been used to reconstruct the excitation energy of the nucleus prior to decay. Comparison of experimental CD cross-section with direct breakup model calculation with neutron in p3/2 orbital favours 34Al(g.s) - νp3/2 as ground state configuration of 35Al. But ground state configuration of 34Al is complicated as evident from γ-ray spectra of 33Al after Coulomb breakup of 34Al. © Owned by the authors, published by EDP Sciences, 2014.
