摘要: Abstract Beta-delayed two-neutron emission from mass-separated samples of short-lived sodium isotopes has been detected both by n-n time correlations with a 4π neutron counter and γ-spectroscopic identification daughter products mass A − 2. The observed cases (intensities per beta decay) are 30 Na (1.2 ± 0.2%), 31 (0.70 0.25%) 32 (5.1 1.8%) . results in good agreement simple model beta-particle emission.
