There has been a significant progress in ab initio approaches to the structure of light nuclei. Starting from realistic twoand three-nucleon interactions the ab initio no-core shell model (NCSM) can predict low-lying levels in p-shell nuclei. It is a challenging task to extend ab initio methods to describe nuclear reactions. In this contribution, we present a brief overview of the the first ste...

We use the auxiliary-fields Monte Carlo method for the shell model in the complete (pf + 0g9/2)-shell to calculate level densities. We introduce parity projection techniques which enable us to calculate the parity dependence of the level density. Results are presented for 56Fe, where the calculated total level density is found to be in remarkable agreement with the experimental level density. T...

The problem of nucleon propagation through the nuclear medium in quasielastic A(e, e ′ p) reactions is discussed in the kinematic range 1 ≤ Q 2 ≤ 7 (GeV/c) 2. Experimental data are available from SLAC, BATES and, recently, also from TJNAF. The coefficient of nuclear transparency is calculated for each Q 2 in the framework of the intranuclear cascade model (INC) and of the eikonal approximation ...

interaction of pb(ii) ion with modified banana shell (mbs) and banana shell (bs) during adsorption fromaqueous solution were investigated. batch experiments were carried out to investigate the effect of contact time,ph, and idmid ion concentration on adsorption efficiency. the favorable pll for maxim= pb(ii) adsorptionwas at 5.0. for the investigated imoi) concentrations (10-80 mph), maximum ad...

Single-reference coupled-cluster theory is an accurate and affordable computational method for the nuclear many-body problem. For open-shell nuclei, reference state typically breaks rotational invariance angular momentum must be restored as a good quantum number. We perform angular-momentum projection after variation employ disentangled formalism Hermitian approach. compare our results with ben...

The presence of a particle continuum, both of a resonant and non-resonant character, can significantly impact spectroscopic properties of weakly bound nuclei and excited nuclear states close to, and above, the particle emission threshold. In the framework of the continuum shell model in the complex momentum-plane, the so-called Gamow Shell Model, we discuss salient effects of the continuum coup...

The differential cross sections of the 208Pb(d, p)2MPb transitions to the states 9/2% 5/2+, l /2+ , 7/2+, and 3/2+ in 209Pb were measured at 135° laboratory angle for deuteron energies between 7.0 and 10.5 MeV. The data below 8.0 MeV were analyzed in COULOMB Wave B O R N Approximation to give accurate spectroscopic factors of the five levels according to a simple shell model potential in the fi...

A theory of the competition between fusion and quasi-fission in a heavy fusing system is proposed, which is based on a master equation and the two-center shell model. Fusion and quasi-fission arise from a diffusion process in an ensemble of nuclear shapes evolving towards the thermal equilibrium. The master equation describes the diffusion of the nuclear shapes due to quantum and thermal fluctu...

We calculate the low-lying spectra of heavy tin isotopes from A = 120 to A = 130 using the 2s1d0g7/20h11/2 shell to define the model space. An effective interaction has been derived using 132Sn as closed core employing perturbative many-body techniques. We start from a nucleon–nucleon potential derived from modern meson exchange models. This potential is in turn renormalized for the given mediu...

Off-energy-shell effects in p - p scattering have been investigated at p - p relative energies from 600 down to 80 keV applying the Trojan horse method (THM) to the p + d --> p + p + n reaction at 5 MeV. In contrast with the on-energy-shell case, no Coulomb-nuclear interference minimum has been found in the extracted THM p - p cross section, due to the suppression of the Coulomb amplitude as pr...
