摘要: Abstract Beta-delayed neutron decay of 33 Na has been studied using the on-line mass separator ISOLDE. The delayed spectra were measured by time-of-flight technique fast scintillators. Two main groups at 800(60) and 1020(80) keV assigned to decay, showing evidence for strong feeding states about 4 MeV in Mg. By simultaneous β–γ–n counting emission probabilities P 1n =47(6)% 2n =13(3)% determined. half-life value Na, T 1/2 =8.0(3) ms , was three different techniques, one employing identifying gamma transitions two beta counting.
