Effects of chiral three-nucleon forces on $^{4}$He-nucleus scattering in a wide range of incident energies

Reanalyses for $^{42-51}$Ca scattering on a $^{12}$C target at $280$ MeV/nucleon based on chiral $g$ folding mode with Gogny-D1S Hartree-Fock-Bogoliubov densities

“…The Kyushu g-matrix folding model is successful in reproducing dσ/dΩ and A y for polarized proton scattering on various targets at E lab = 65 MeV [6] and dσ/dΩ for 4 He scattering at E lab = 72 MeV per nucleon [7]. This is true for σ R of 4 He scattering in E lab = 30 ∼ 200 MeV per nucleon [8] and of 40 Ca+ 12 C scattering at E lab = 280 MeV per nucleon [15].…”

“…Background on g-matrix folding model. The g-matrix folding model [1][2][3][4][5][6][7][8][9][10][11] is a standard way of deriving microscopic optical potentials of elastic scattering. In the model, the potential is obtained by folding the g-matrix with projectile and target densities.…”

“…Kohno calculated the g matrix for the symmetric nuclear matter, using the Brueckner-Hartree-Fock method with chiral N 3 LO 2NFs and NNLO 3NFs [12]. He set c D = −2.5 and c E = 0.25 so that the energy per nucleon can become minimum at ρ = ρ 0 [8].…”

“…[15], we predicted r p , r n , r m , r skin for 40−60,62,64 Ca after determining the neutron dripline, using the Gogny-D1S Hartree-Fock-Bogoliubov (GHFB) with and without the angular momentum projection (AMP). Using the Kyushu (chiral) g-matrix folding model [6][7][8], we also predicted reaction cross section σ R for 40−60,62,64 Ca scattering on a 12 C target at 280 MeV/nucleon, since Tanaka el al. measured σ I for 42−51 Ca.…”

Determination of matter radius and neutron skin of $^{58}$Ni from reaction cross section of proton+$^{58}$Ni scattering based on chiral $g$-matrix model

“…Recently, we have determined r m and r skin for 208 Pb [5] and 40,48 Ca [6,7], using the chiral (Kyushu) g-matrix folding model with the densities calculated with Gogny-D1S-HFB (GHFB) with the angular momentum projection (AMP). As for 58 Ni, the data on σ R are available * orion093g@gmail.com for p+ 58 Ni scattering [8][9][10][11][12] The g-matrix folding model is a standard way of obtaining microscopic optical potential for proton scattering and nucleus-nucleus scattering [13][14][15][16][17][18][19][20][21][22]. Applying the folding model with the Melbourne g-matrix [16] for σ I for Ne isotopes and σ R for Mg isotopes, we found that 31 Ne is a deformed halo nucleus [23], and determined the matter radii r m for Ne isotopes [2] and for Mg isotopes [3].…”
