Quasi-free knockout reactions in inverse kinematics offer great opportunities to probe the mean-field properties of imbalanced nuclei. We have developed a reaction model for quasi-free A(p, pN)B reactions with unstable nuclei. Such a model makes it possible to connect experimental data from (p, pN) measurements in inverse kinematics at radioactive-beam facilities, to the mean-field properties...

In the present work the photoneutron reactions of Sn and (p,n) reaction on Indium for Tin isotopes production will be analyzed. For both processes the cross sections for energy of incident particles of order of MeV’s were estimated. The contributions of different nuclear reaction mechanisms and the corresponding influence of nuclear potentials in the cross sections were obtained. The cross...

We propose a new approach for the treatment of isovector pairing in self-consistent mean field calculations which conserves exactly the isospin and the particle number in the pairing channel. The mean field is generated by a Skyrme-HF functional while the isovector pairing correlations are described in terms of quartets formed by two neutrons and two protons coupled to the total isospin T=0....

Nuclear track emulsion (NTE) is still retaining its exceptional position as a means for studying the structure of diffractive dissociation of relativistic nuclei owing to the completeness of observation of fragment ensembles and owing to its record spatial resolution. Separation of products of fragmentation and charge-exchange reactions of accelerated stable nuclei make it possible to create...

Pairing phenomena emerge in nuclear structure and in reactions involving a transfer of correlated pairs. We will give an account of the studies on this topic that have been carried on at our institute in collaboration with several other groups. The low-lying bound ground state and continuum states of 6He are constructed starting from neutron single-particle unbound p-resonances of the 5He...

The recent progresses in the development of ab initio approaches make possible the description of bound and scattering states for light nuclear systems in a unified framework, based on microscopic Hamiltonians built within chiral effective theory. Among these approaches, the No-Core Shell Model with Continuum (NCSMC) [1] has proven particularly successful for studying resonances and elastic...

The half-lives of yrast states in 86,87Rb isotopes, produced in 82Se(7Li, xn) reactions, were measured using the ROSPHERE gamma spectrometer. The experimental evidences prior to this measurements lead to the conclusion that 1p-2h proton configurations which involve the g9/2, f5/2, p3/2 orbitals are energetically favored to appear in this mass region with N~50 for states at excitation energies...

The study of beta-delayed decay modes of nuclei near the proton drip line is pivotal for nuclear-structure physics in understanding the role of isospin impurity in the states of outermost imbalance of the proton and neutron numbers with respect to stable nuclei. The mechanism of a beta-delayed decay involves first a beta decay, with the highest probability for a superallowed beta-decay to the...
