One - Neutron Halo of ~ 9
We have measured the longitudinal momentum distribution of ' C, ' C, and ' C after the one-neutron breakup of ' C, ' C, and "C, respectively, using the A1200 fragment separator as an energy-loss spectrometer. The observed narrow width of 44.3 +. 5.9 MeV/c for the "C fragments indicates that ' C is a new example of a one-neutron halo, so far the heaviest ever observed. The consequences of the ob...

متن کاملFusion reactions with the one-neutron halo nucleus (15)C.
The structure of (15)C, with an s(1/2) neutron weakly bound to a closed-neutron shell nucleus (14)C, makes it a prime candidate for a one-neutron halo nucleus. We have for the first time studied the cross section for the fusion-fission reaction (15)C+(232)Th at energies in the vicinity of the Coulomb barrier and compared it to the yield of the neighboring (14)C+(232)Th system measured in the sa...

متن کاملHyperfine structure constant of the neutron halo nucleus (11)Be(+).
The hyperfine splittings of ground state Be+11 have been measured precisely by laser-microwave double resonance spectroscopy for trapped and laser cooled beryllium ions. The ions were produced at relativistic energies and subsequently slowed down and trapped at mK temperatures. The magnetic hyperfine structure constant of Be+11 was determined to be A11=-2677.302 988(72) MHz from the measuremen...
