The traditional interpretation of pairs of nucleons coupled to angular momentum 0 and 2 as bosons in the Interacting Boson Model is revisited. In contrast to previous calculations, where extensive use of the Number Operator Approximation (N.O.A.) is made, we show new calculations of spectroscopic intensities of one nucleon transfer reactions and log ft values of single beta decays where this...

We present a phase-space representation of quantum state vectors for two-cluster systems which is valid both for finite hbar and when hbar goes to zero. The Bargmann-Segal transformation was used to map wave functions of two-cluster systems in the coordinate space into the Fock-Bargmann space. The density distribution in the phase space was compared with those in the coordinate and momentum...

Precise understanding of nuclear interaction is the basis for correct description of properties of nuclei and reactions involving them. Systems of three nucleons (3N) can be treated as a testing ground for the modern approaches to describe nuclear interaction, since for them exact theoretical calculations can be performed. At intermediate energies, observables for 3N systems are sensitive to...

A series of experiments studying a few nucleon systems in continuum of 3-body final states was performed at KVI Groningen with the use of BINA detector. The studies were mainly devoted to the system of three nucleons. The differential cross section data obtained for d(1H,pp)n reaction at beam energy of 160 MeV (80 MeV/nucleon)will be presented and compared to the state-of-the-art calculations,...

One-neutron transfer reactions A(d,p)B are often described by a three-body n+p+A model due to importance of deuteron breakup. All models used to treat this breakup assume that the two-body n-A and p-A interactions are described by the corresponding local optical potentials taken at half the deuteron energy. The present talk shows that projection of the n+p+A many-body function into the...

BINA is an experimental setup with a nearly 4π geometrical acceptance that has been developed in 2004 at KVI and designed for studying three- and four-nucleon scattering processes. BINA is composed of two main parts, a forward wall and the backward ball. The forward wall consists of two components, namely a hodoscope of segmented thin and thick scintillators and a Multi Wire Proportional...

Experimental differential cross sections of proton deuteron radiative capture and the photo-disintegration of 3He are compared at the same center of mass angle as a function of energy. The proton deuteron radiative capture (PDRC) differential cross sections are multiplied by an appropriate detailed-balance factor. For Eγ > 50 MeV the PDRC results have good agreement with the inverse reaction...

QCD-based effective field theories are becoming increasingly more powerful in describing few-body nuclear systems. These models establish a quantitative relationship between muon capture rates and fundamental astrophysical processes from which cross sections can not be measured in the laboratory, such as pp fusion in our sun. The MuSun experiment is measuring the muon capture rate on the...
