Properties of 3.89/3.96-MeV states in 11Be
نویسندگان
چکیده
I have reanalyzed previous data from the 9Be(t,p) reaction to extract energies and widths for the two states near 3.9 MeV. Results are energies of 3889.27 ± 1.03 and 3954.53 ± 1.16 and widths of 3.2(8) and 7.9(7), all in keV, for the 5/2− and 3/2− states, respectively.

Comment on “ Neutron knockout of 12 Be populating neutron - unbound states in 11 Be ”
A recent paper [Phys. Rev. C 83, 057304 (2011)] used knockout from 12Be to populate two states near 3.9 MeV in 11Be and observed their neutron decay—but treated the two as a single state. The authors used a branching ratio for the upper state from an experiment that also did not separate the two states. Thus, their energy for 11Be(3.96 MeV) and the spectroscopic factor connecting it to 12Be(gs)...
متن کاملNeutron Widths and Configuration Mixing in 11Be
We use known widths and branching ratios in 11Be to discuss Jπ and configuration admixtures. Analysis favors 3/2− for the 3.96-MeV state and three-state mixing for this Jπ .

متن کاملEvidence Of A ( 1 d 5 / 2 ) 2 Component To The 12 Be Ground State
Data have been obtained on exclusive single neutron knockout cross sections from 12Be to study its ground state structure. The cross sections for the production of 11Be in its ground state (1/2+) and first excited state (0.32 MeV, 1/2−) have previously been measured [1], indicating a strong (2s1/2) 2 component to the 12Be ground state. In the present experiment, performed at the GANIL laborator...
متن کاملOne-neutron knockout from individual single-particle states of 11Be
The structure of the halo nucleus 11Be has been studied using the reaction 9Be(11Be,10Be+gamma)X at 60 MeV/nucleon. The ground state structure of 11Be is determined by comparing the experimental cross sections to a calculation combining spectroscopic factors from the shell model with l-dependent single-particle cross sections obtained in an eikonal model. This experiment shows the dominant 1s s...
متن کاملDirect evidence for the breakdown of the N = 8 shell closure in 12Be
Partial cross sections and corresponding momentum distributions have been studied in the one-neutron knockout reaction ( 12Be,11Be+gamma) on a 9Be target at 78 MeV/nucleon. The resulting spectroscopic factors for the only two bound states of 11Be are 0.42+/-0.06 ( 1/2(+)) and 0.37+/-0.06 ( 1/2(-)), where the errors are experimental only. This result shows that N = 8 is not a good closed shell i...
