Spectroscopic factors were extracted relative to the simultaneously measured calibration reaction 208Pb d, 3He 207Tl. Series Statement Early English books, 1475-1640 ; 1524:1 Other Forms Also available online. For the and multiplets uncertainties are larger because of assumptions of some of the spins for the states of high excitation energy. They discuss in particular, mainly for the case of nuclei, the quasihole strength z spectroscopic factor that gives the probability of the quasiparticle's being a physical particle. The difference between physical particles and quasiparticles results from the effects of correlations in the system. Broad, unresolved structures between 3 MeV and 10 MeV excitation energy were attributed to the deeply bound, highly fragmented 1f shell. Despite of the obvious success of the nuclear shell model the occupation numbers of nucleons in the shell model orbitals could not be determined precisely.

The mean field concept to describe properties of nuclear states has been rather successful in the energy range around the Fermi surface, which represents the classical low-energy, low-momentum regime. The need of a combined analysis of high resolution experiments is also emphasized. The comparison with shell model calculations give only rough agreement as they predict the energies of the respective states about 300 keV too high. Single-particle densities derived from these wave functions are in qualitative agreement with measured charge and mass densities for 208Pb. The spin-orbit splittings deduced from 58 measured single-particle energies of bound protons and neutrons in closed shell nuclei show besides the trivial 2l + 1 -proportionality a simple dependence on the number of node of the radial wavefunction main quantum number n and on the mass number A of the respective core. For the present setting, where the recoil momentum is almost zero, an averaged density seen through this reaction can be estimated and it reaches almost half of the saturation density in some cases.

Spins and parities of states in 83Br and 85Br were determined from angular distributions of cross sections σ θ and analyzing powers iT11 θ measured in the , 3He reaction on 84Kr and 86Kr. It is expected that the correlation functions from different potentials can be selected and an understanding of the in-medium properties of nucleon pairs will be gained. The low-energy states of nearly closed-shell systems can be interpreted as having quasiparticles in single-particle orbitals. The Ay values are reduced from those of free proton-proton scattering and the reduction rate is found to depend on target.

Die Messungen haben gezeigt, daß die Bindungsenergien der Nukleonen in den verschiedenen Schalen und die Spin-Bahn-Aufspaltungen einer einfachen Systematik folgen.

Spectroscopic factors were extracted relative to the simultaneously measured calibration reaction 208Pb d, 3He 207Tl. The deduced inclusion into one of the four multiplets put limits on the possible spins of the states in question.

The magnetic dipole state at 5. The deduced J-dependence of the matrix elements differs from those found in other systematic investigations indicating more complicated underlying nuclear forces must contribute. The interpretation of one-nucleon transfer and quasi-free knock-out experiments, the classical tools for nuclear structure studies, did not yield reliable absolute spectroscopic factors mainly because of the uncertain distortions.

It is expected that the correlation functions from different potentials can be selected and an understanding of the in-medium properties of nucleon pairs will be gained. On the other hand, elastic electron scattering represents a high precision tool to study nuclear charge density distributions which, however, offers no direct model-independent access to occupation numbers.

The matrix elements of the two-body residual interaction were derived unambiguously for the multiplets. The new generation of high resolution experiments on 160 with real and virtual photons permits a stringent state-by-state comparison of measured momentum distributions with various model calculations.

The lowest moments of the proton strength distributions observed in pickup and stripping experiments on a number of nuclei in the Zr region were determined and systematic properties of single particle energies and spreading widths were deduced. As result, a set of orthogonal proton and neutron wave functions was obtained which were used for a consistent reanalysis of proton and neutron single-particle transfer reactions on 208Pb. The magnetic dipole state at 5. Results from both theory and experiment indicate that z~0. The data reveal a simple linear dependence on mass number A and isospin To of the target nuclei which can be interpreted in terms of an extended Bansal-French model. .
