Study of the $\beta$-decay of $^{11}$Li at ISAC/TRIUMF
ORAL
Abstract
The $\beta$-decay of $^{11}$Li was investigated using the 8$\pi$ $\beta$-decay spectrometer, an array of 20 Compton-suppressed HPGe detectors and 20 plastic scintillators for $\beta$-particle detection. Doppler-broadened line shapes resulting from the decay of excited states of $^{10}$Be populated by $\beta$-delayed neutron emission are analyzed using Monte Carlo simulations. New $\beta$-delayed neutron decay branches are shown to contribute to the complex decay of $^{11}$Li. Results, comparison with previous works, as well as implications for the beta-decay of the $^{11}$Li halo neutrons will be discussed.
