Dipole Strength Distribution of He 8 and Decay Characteristics

C. Lehr, T. Aumann, M. Duer, A. T. Saito et autres

The weak binding and spatially extended neutron densities characteristic of drip-line nuclei give rise to a distinctive low-energy dipole response. The drip-line nucleus ^{8}He is the most neutron-rich bound nucleus with a mass-to-charge ratio of A/Z=4. We measure the dipole response of …

Direct observation of three-neutron emission from He * 7 and the search for the trineutron

S.W. Huang, C. Lenain, Z. Yang, F. M. Marqués et autres

Three-neutron emission from He 7 has been directly measured for the first time, following neutron knockout from a He 8 beam at 156 MeV/nucleon. A resonancelike structure at 2.08(4) MeV above the He 4 + 3 n threshold [ E x = …

Unbound neutron $\nu0d_{3/2}$ strength in $^{17}$C and the N=16 shell gap

J. Lois-Fuentes, B. Fernández–Domínguez, F. Delaunay, X. Pereira-López et autres

Significant continuum strength has been observed to be populated in $^{17}$C produced in the d($^{16}$C,p) reaction at a beam energy of 17.2~MeV/nucleon. The strength appears at greater than $\sim$2~MeV above the single-neutron decay threshold and has been identified as arising from transfer …

Probing Exotic Cross-Shell Interactions at N = 28 with Single-Neutron Transfer on K 47

C. Paxman, A. Matta, W. N. Catford, G. Lotay et autres

We present the first measurement of the ^{47}K(d,pγ)^{48}K transfer reaction, performed in inverse kinematics using a reaccelerated beam of ^{47}K. The level scheme of ^{48}K has been greatly extended, with nine new bound excited states identified and spectroscopic factors deduced. Uniquely, the …

Low-energy neutron cross-talk between organic scintillator detectors

M. Sénoville, F. Delaunay, L. Achouri, N. A. Orr et autres

A series of measurements have been performed with low-energy monoenergetic neutrons to characterise cross-talk between two organic scintillator detectors. Cross-talk time-of-flight spectra and probabilities were determined for neutron energies from 1.4 to 15.5 MeV and effective scattering angles ranging from ∼ 50 …

Magicity versus Superfluidity around O 28 viewed from the Study of F 30

J. Kahlbow, T. Aumann, O. Sorlin, Y. Kondo et autres

The neutron-rich unbound fluorine isotope ^{30}F_{21} has been observed for the first time by measuring its neutron decay at the SAMURAI spectrometer (RIBF, RIKEN) in the quasifree proton knockout reaction of ^{31}Ne nuclei at 235 MeV/nucleon. The mass and thus one-neutron-separation energy …

Evolution of the two-neutron configuration from 11Li to 13Li

Paul André, A. Corsi, A. Revel, Y. Kubota et autres

In this work we investigate the two-neutron decay of 13 Li and of the excited states of 11 Li populated via one-proton removal from 14 Be and 12 Be, respectively. A phenomenological model is used to describe the decay of 11 Li …

Mass, Spectroscopy, and Two-Neutron Decay of Be16

B. Monteagudo, F. M. Marqués, J. Gibelin, N. A. Orr et autres

The structure and decay of the most neutron-rich beryllium isotope, ^{16}Be, has been investigated following proton knockout from a high-energy ^{17}B beam. Two relatively narrow resonances were observed for the first time, with energies of 0.84(3) and 2.15(5) MeV above the two-neutron …
