چکیده

The single-nucleon knockout reactions Be(B,B1g)X and Au(B,B1g)X , at an incident energy of 60 MeV per nucleon, have been used to probe the structure of B and of the core fragment B. A dominant 2s configuration is deduced for the neutron in the ground state of B. The longitudinal momentum distribution for this state is consistent with ‘‘neutron halo’’ structure. Spin assignments for B excited states at 3.48 and 3.68 MeV are proposed based on the observed spectroscopic factors for one-neutron removal.

Experimental Studies of Unbound Neutron-rich Nuclei

The three-body description of two-neutron halo nuclei relies on the two-body interactions between the constituents. In order to provide constraints on calculations devoted to 14 Be and 17 B, the neutron unbound states of 13 Be and 16 B have been investigated by one-proton knockout. The experimental techniques and results are discussed here.

Two-proton knockout on neutron-rich nuclei

Two-proton knockout reactions on neutron-rich nuclei [1] have been studied in inverse kinematics at intermediate energy. Strong evidence that the two-proton removal from a neutron-rich system proceeds as a direct reaction is presented, together with a preliminary theoretical discussion of the partial cross sections based on eikonal reaction theory and the many-body shell model. They show that t...

Synthesis of spirooxindole derivatives catalyzed by Fe (III)@graphitic carbon nitride nanocomposite via one-pot multi-component reaction

Fe (III) supported graphitic carbon nitride nanocomposite was synthesized by impregnation of FeCl3 with g- C3N4 (Fe (III)@g-C3N4). Then, the synthesis of spirooxindole derivatives was carried out in the presence of Fe (III) @ graphitic carbon nitride nanocompositevia the multi-component reaction of malononitrile, isatins, and 1,3...

Diffraction dissociation contributions to two-nucleon knockout reactions and the suppression of shell-model strength

The contributions to the cross sections of intermediate energy two-nucleon knockout reactions from events in which one nucleon is removed by the stripping (inelastic breakup) mechanism and a second by the diffraction (elastic breakup) mechanism are discussed. The small additional contributions from two-nucleon diffraction events are also estimated. The approach used combines the eikonal reactio...
