摘要: Abstract The Pn values for 9Li and 11Li were determined to be (50 ± 4)% (95 8)%, respectively, by a beta-neutron coincidence technique. of 27–31Na, 93–98Rb 145–146Cs, which had been deduced normalization the older value 9Li, should thus raised factor 1.43. β-decay branch 320 keV first excited state 11Be was found (9.2 0.7)%. fraction one-neutron emission leading states 10Be (41 4)%. half-life remeasured (8.83 0.12)ms.
