Abstract

The γ-ray spectrum following β-decay of ¹¹Li has been remeasured at the ISOLDE facility at CERN. Two new transitions were observed through the use of large Ge-detectors. Most γ-decays will follow β-delayed neutron emission. Information on the energy of the neutron is derived from analysis of the γ line-shape and used to construct a partial decay scheme for ¹¹Li. Lifetime values for the 1^- and 2^- levels in ¹⁰Be are also derived. A new partial decay scheme is presented.
