Abstract

The β-decay of 12N is used to populate α-emitting excited states in 12C. The α-particles from the break-up of both the 10.3 MeV and 12.71 MeV states were measured in coincidence with an efficient detector setup consisting of two double-sided Si strip detectors. The break-up of the 12.71 MeV 1- state is an interesting testing ground for the different descriptions of multi-particle break-up, whereas the properties of the 10.3 MeV state, which under some astrophysical conditions is relevant for the production of 12C in stars, are poorly known. First results from the analysis of the data is presented and compared with Monte Carlo simulations.
