New information on $\beta$-delayed neutron emission from $^{12, 14}$Be
The $\beta$-delayed neutron branches from neutron-rich Be-isotopes have been measured with a setup sensitive down to thermal energies. For $^{14}$Be a new value of P$_{n}$= 101 $\pm$ 4% has been found for the total neutron-emission probability and an upper limit of 2.4% (95% confidence level) is imp...
