“…On the other hand, the TST processes are dominant for the j-forbidden state data. This agrees with the results of previous studies where rough agreements with experimental data were obtained with only TST processes treated for the transfer to the excited states [25]. But the contributions from OST processes are also visible, especially for 28 Si and 40 Ca, for which the OST contribute considerably at forward and at all angles, respectively.…”

“…data of 28 Si at forward angles where the SAs of G2 do not reproduce the experimental data as well as those of G1 (although they give very similar χ 2 values), calculations with both groups of SAs repro- duced the experimental data nearly equally well. These calculations considerably improved the reproduction of the experimental data as compared with those reported in the original paper [25]. Values of spectroscopic amplitudes from available shell model calculations are also given in Table.II for comparisons with the experimental ones.…”

“…In order to study the feasibility of extracting the SAs of HLSPCs in the ground and low excited state of nuclei, we reanalyze the (p, d) reactions measured by Ohnuma et al [25] at 51.93 MeV with 12 C, 24 Mg, 28 Si and 40 Ca leading to the j-forbidden states at 4.32 MeV ( 5 2 − ) in 11 C, 2.05 MeV ( 7 2 + ) in 23 Mg, 2.16 MeV ( 7 2 + ) in 27 Si, and 3.64 MeV ( 9 2 − ) in 39 Ca. One step transfer to the ground states (g.s.)…”

“…via collective excitations of the target and of the residual were included in Ref. [25]. In addition to these processes, we include direct OST to the j-forbidden excited states, assuming the transferred neutrons initially populate the HLSPCs in the ground states of the target nuclei.…”

A detailed feasibility study on deducing the high-lying single-particle components (HLSPCs), which are important but used to be ignored, in the ground and low-lying excited states of even-even light nuclei is performed by analyses of (p, d) reactions with 12 C, 24 Mg, 28 Si, and 40 Ca targets at 51.93 MeV. Coupled reaction channels (CRC) analyses have been made for (p, d) transitions to the j-forbidden excited states in 11 C ( 5 2 − , 4.32 MeV), 23 Mg ( 7 2 + , 2.05 MeV), 27 Si ( 7 2 + , 2.16 MeV) and 39 Ca ( 9 2 − , 3.64 MeV), including the major allowed transition components together with direct components of HLSPCs. Spectroscopic amplitudes of the HLSPCs are deduced by fitting the angular distributions of the ground and the j-forbidden excited states simultaneously. The present analysis demonstrates for the first time that information about HLSPCs in atomic nuclei can be obtained from analysis of (p, d) reactions.

“…In Fig. 5, the cross sections for the elastic scattering data of 35 MeV [25], 51.93 MeV [26], 120 MeV [27], and 250 MeV [28] protons from 12 C are compared with the results of our model. As shown in the figure, the results of the modified model are in good agreement with the experimental data except for the large angle parts, mostly due to low statistics (1,000,000 events for each case).…”

We implement the Heisenberg principle into the Constrained Molecular Dynamics (CoMD) model with a similar approach to the Pauli principle using the one-body occupation probabilityfi. Results of the modified and the original model with comparisons to data are given. The binding energies and the radii of light nuclei obtained with the modified model are more consistent to the experimental data than the original one. The collision term and the density distribution are tested through a comparison to p+ 12 C elastic scattering data. Some simulations for fragmentation and superheavy nuclei production are also discussed.
