Observation of a p-wave one-neutron halo configuration in (37)Mg.
Cross sections of 1n-removal reactions from the neutron-rich nucleus (37)Mg on C and Pb targets and the parallel momentum distributions of the (37)Mg residues from the C target have been measured at 240 MeV/nucleon. A combined analysis of these distinct nuclear- and Coulomb-dominated reaction data shows that the (37)Mg ground state has a small 1n separation energy of 0.22(-0.09)(+0.12) MeV an...
متن کاملOne - 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 کاملOptimal observation of the one-dimensional wave equation
In this paper, we consider the homogeneous one-dimensional wave equation on [0, π] with Dirichlet boundary conditions, and observe its solutions on a subset ω of [0, π]. Let L ∈ (0, 1). We investigate the problem of maximizing the observability constant, or its asymptotic average in time, over all possible subsets ω of [0, π] of Lebesgue measure Lπ. We solve this problem by means of Fourier ser...
