Neutron removal from the deformed halo nucleus Ne31

2017

Experimental data on Coulomb breakup and neutron removal indicate that 31 Ne is one of the heaviest halo nuclei discovered so far. The possible ground state of 31 Ne is either 3/2 − coming from p-wave halo or 1/2 + from s-wave halo. In this work, we develop a treatable model to include deformed wave functions and a dynamical knockout formalism which includes the dependence on the nuclear orientation to study the neutron removal from 31 Ne projectiles at energies around E ≈ 200 MeV/nucleon. A detailed account of the effects of deformation on cross sections and longitudinal momentum distributions is made. Our numerical analysis indicates a preference for the 31 Ne ground state with spin parity 3/2 − .

“…3 We believe that this is preferable to the commonly adopted procedure whereby the theoretical lineshapes are normalised to the peak of the experimental distribution. 4 These may arise from effects not incorporated in the model employed here [41,42], the choice of the model or formalism (see, for example, refs. [43,44]) and uncertainties in the parameters of the model itself.…”

Re-examining the transition into the N = 20 island of inversion: Structure of 30Mg

et al. 2018

Intermediate energy single-neutron removal from 31 Mg has been employed to investigate the transition into the N=20 island of inversion. Levels up to 5 MeV excitation energy in 30 Mg were populated and spin-parity assignments were inferred from the corresponding longitudinal momentum distributions and γ-ray decay scheme. Comparison with eikonal-model calculations also permitted spectroscopic factors to be deduced. Surprisingly, the 0 + 2 level in 30 Mg was found to have a strength much weaker than expected in the conventional picture of a predominantly 2p − 2h intruder configuration having a large overlap with the deformed 31 Mg ground state. In addition, negative parity levels were identified for the first time in 30 Mg, one of which is located at low excitation energy. The results are discussed in the light of shell-model calculations employing two newly developed approaches with markedly different descriptions of the structure of 30 Mg. It is concluded that the cross-shell effects in the region of the island of inversion at Z=12 are considerably more complex than previously thought and that np − nh configurations play a major role in the structure of 30 Mg.

The overlap functions between the nuclear wave functions in initial and final states are important structural quantities that enter the amplitudes of nuclear reactions such as transfer, knockout and radiative capture. They carry information about the single-particle structure and about the nucleonnucleon interactions and correlations in atomic nuclei. The current status of knowledge of overlap functions is reviewed with an emphasis on their theoretical calculation. The open problems associated with their prediction are highlighted and challenges are discussed.
