本文首次报道了利用一种特别适合于研究反运动学放射性光束反应的新型光谱仪——螺旋轨道光谱仪HELIOS的实验。用较好的分辨率研究了富中子N=8核13B中一些低洼态的性质。根据测量的（d,p）反应的角分布和相对光谱因子，可以约束该核的第一激发态和第三激发态的自旋和构型分配。
A first experiment is reported that makes use of a new kind of spectrometer uniquely suited to the study of reactions with radioactive beams in inverse kinematics, the helical orbit spectrometer, HELIOS. The properties of some low-lying states in the neutron-rich N=8 nucleus 13B were studied with good resolution. From the measured angular distributions of the (d,p) reaction and the relative spectroscopic factors, spin and configuration assignments of the first- and third-excited states of this nucleus can be constrained.
