Abstract: The beta-delayed charged particle spectra from 6He and 8He were measured with a telescope consisting of a gas counter and a Si surface barrier detector. Beta-delayed deuterons and tritons are emitted in the two cases with branching ratios of (7.6 ± 0.6)×10−6, Ed > 350 keV and (8.0 ± 0.5)×10−3, respectively. Both spectra present anomalies that must be due to the special structure of these nuclei (an alpha core surrounded by several neutrons).
