“…These developments in reaction theory must consider the adequate treatment of the reaction dynamics, realistic structure models and proper effective interactions. Some of the newer approaches include the improved quantum molecular dynamics (ImQMD) model [52][53][54][55][56] and time-dependent Hartree-Fock (TDHF) theory [57][58][59][60][61][62][63][64][65][66]. Nowadays it is possible to take into account quantal fluctuations and correlations going beyond the TDFH approach [67][68][69][70].…”

Multinucleon transfer reactions, characterized by the exchange of many nucleons at energies in the vicinity of the Coulomb barrier, have been extensively used in the last decades to understand the production of neutron-rich nuclei, as well as to study their structure. In this Mini Review, recent results related to the production mechanism of heavy neutron-rich nuclei obtained with stable and radioactive beams will be discussed together with the results concerning the proton transfer channels. Additionally, newest results from a series of experiments carried out to study nucleon-nucleon correlations for closed-shell and superfluid systems employing the large solid angle magnetic spectrometer PRISMA will be summarized.

“…These new studies are receiving a distinctive boost thanks to the successful implementation of large solid angle magnetic spectrometers, which allow to identify in mass, charge, and Q value and with unprecedented efficiency multinucleon transfer products. The experimental high-quality data accumulated so far on the relevant observables [6][7][8][9][10][11][12][13][14], in particular cross sections, also helped to test and improve the predictions of the various theoretical models [15][16][17][18][19][20]. However, such studies are still limited to very few cases and an effort is required to explore a wider range of bombarding energies and masses.…”

Transfer reactions in Pb206+Sn118 : From quasielastic to deep-inelastic processes

We measured multinucleon transfer reactions for the 206 Pb + 118 Sn system at E lab = 1200 MeV by employing the large solid angle magnetic spectrometer PRISMA. Differential and total cross sections and Q-value distributions have been obtained for a variety of neutron and proton pick-up and stripping channels. The Q-value distributions show how the quasielastic and deep inelastic processes depend on the mass and charge of the transfer products. The corresponding cross sections have been compared with calculations performed with the GRAZING code. An overall good agreement is found for most of the few nucleon transfer channels. The underestimation of the data for channels involving a large number of transferred nucleons indicates that more complicated processes populate the given isotopes.

“…Calculations based on the Langevin type dynamical equations of motion suggest the 136 Xe + 208 Pb reactions at energies around the Coulomb barrier, in which more than 50 unknown nuclei might be produced with cross sections not less than 1 μb [6]. Then, the isotopic, mass, and energy distributions of the fragments in those reactions were measured at Dubna and Argonne [7,8], providing data to test models for multinucleon transfer, such as GRAZING, the Langevin model, the improved quantum molecular dynamics model [9,10], and the dinuclear system model [11].…”

Many isotopes of Np, Pu, Am and Cm around N = 126 shell still have not been produced in the laboratory. This work with the aims to investigate the cross sections and yields of the neutron-deficient nuclei Np, Pu, Am and Cm produced in the proton-induced spallations of transuranium element. The isospin-dependent quantum molecular dynamics (IQMD) model is applied to study the dynamical process of reaction, and the subsequent decay process is simulated by the GEMINI++ model. The IQMD-GEMINI++ model is applied to calculate the cross section, kinetic energy and angle distribution of the isotopic productions around N=126. The Lindhand Scharff and Schiott theory is applied to calculate the energy loss of different heavy nuclei in target material. Comparison between the data and calculations shows that the IQMD-GEMINI++ model can reproduce the production cross section of the neutron-deficient nuclei in spallation within 1 order of magnitude approximately. The maximum cross section of undiscovered isotope of Np, Pu, Am and Cm is about $10^{-5} $ mb, while the kinetic energy of productions are all less than 16 MeV. The angle distribution shows that the emission direction of production is in the forward downward angle mostly. The range of the production in the target is within the range of $10^{-7}$ to $10^{-5} $ cm. This range is effective target thickness for online identification of the undiscovered isotope. Based on the effective thickness of the target and assuming a intensity 120 $\mu$A of the proton beam, the yields of the undiscovered neutron-deficient nuclei are calculated. Productions of the undiscovered isotope of Np, Pu, Am and Cm by the proton-induced spallation of transuranium element are feasible. However, the experimental techniques for on-line identification of the neutron-deficient nuclei produced in the proton-induced spallation should be developed.
