Abstract

Experimental studies of β-decay measurements of the neutron drip line nuclei ¹¹Li and ¹⁴Be are presented. β-decay schemes of these nuclei are determined by measuring β-rays, delayed neutrons and γ-rays in triple coincidence. The decay schemes of both ¹¹Li and ¹⁴Be associated with single neutron emission are unambiguously determined. New levels in their daughter nuclei, ¹¹Be and ¹⁴B, are found. In addition, the deduced level scheme of ¹⁴B indicates the lowering of 2s_1/2 single neutron orbital with respect to 1p_1/2 orbital in the N=9 isotones. Such behavior is known to exist in N=7.
