Îł-ray spectroscopy of C19 via the single-neutron knock-out reaction
The one-neutron knock-out reaction H-1(C-20, C-19 gamma) was studied at RIKEN using the DALI2 array. A gamma-ray transition was observed at 198(10) keV. Based on the comparison between the experimental production cross section and theoretical predictions, the transition was assigned to the de-excitation of the 3/2(1)(+) state to the ground state
Nuclear structure study of 19,20,21N nuclei by gamma spectroscopy
The structure of neutron rich nitrogen nuclei has been studied by use of
neutron removal reaction and inelastic scattering. Mass and charge deformations
have been deduced for the first excited state of 21N, which indicates the
partial persitence of the N=14 subshell closure in nitrogen isotopes. The
spectroscopic information obtained on the structure of 19,20,21N confirms the
results from a previous experiment
