Diproton correlation in a proton-rich Borromean nucleus 17Ne Tomohiro OishiA, Kouichi HaginoA, Hiroyuki SagawaB ATohoku Univ., BUniv. of Aizu 1. Introduction 2. Model 3. Results 4. Summary http://arxiv.org/abs/1007.0835

1.1 Dineutron correlation Dineutron correlation in 2n-Borromean nuclei (theoretically predicted): K.Hagino, and H.Sagawa, PRC72(‘05)044321 Remarkable localization of two neutrons “dineutron correlation”. How about two protons in a weakly bound system?

1.2 17Ne nucleus (1)

1.2 17Ne nucleus (2) Typical “2p-Borromean” nucleus; proton-unbound, stable for proton emission. 17Ne is an ideal system to analyze diproton correlation.

2.1 Three-body-model Off-diagonal

2.2 Pairing interaction Explicit Coulomb interaction Density-dependent contact interaction We need cutoff:EC to determine v0 (pairing in vacuum). Other parameters are fixed to obtain g.s.energy of 17Ne:-0.944 MeV.

2.3 Single-particle basis Woods-Saxon + Coulomb potential for p-Core

Averaged Resonances

2.3 Box-approximation Put infinite wall at r=Rbox:  Continuum states are discretized. Resonances of 16F at 0.675 MeV (s1/2) and at 1.129 MeV (d5/2) are reproduced.

2.5 Expansion with s.p.basis Determined by diagonalization 0+ configuration for g.s.

3.1 Results (1)

Pairing gap of protons and neutrons S.Hilaire et al., Phys.Lett.B531(2002) Pairing gap of protons and neutrons protons neutrons

3.2 Results (2) “Diproton correlation”

4. Summary We performed three-body-model calculation for 17Ne with density-dependent contact pairing and the Coulomb interaction. Coulomb repulsion contributes about 14% reduction to pairing energy. Existence of strong “diproton correlation”. Future works: application to 2p-emission.
