The physics questions that can be addressed through beta decays of exotic nuclei are reviewed. They cover fundamental tests, nuclear astrophysics, nuclear spectroscopy, nuclear halo states and in particular beta-delayed particle emission processes. The basic theory is reviewed briefly and trends in

β¦ Synopsis
The recent progress in studies of fl-decays of drip-line nuclei possessing halo states is presented. The main emphasis is on the decay of 11Li, which has a well-established halo structure in its ground-state. Experimental results are from the ISOLDE Facility at CERN. The observation of beta-delayed deuteron emission from llLi as well as implicalions of the measured HLi fl-strength function for its halo structure are discussed.
Studies of unbound nuclear states which are related to the halo nuclei via simple operations like isobaric analogues or mirror states. The last case is illustrated on results from studies at GANIL of the unbound nucleus 1iN, the mirror of the halo nucleus HBe.

Even though being the subject of intense scrutiny during the last decade halo nuclei still offer unanswered questions. One way of adding confidence to the conclusions obtained in the often difficult experiments is to probe the same physical observable in various ways. The prominent example in this
