The basic assumption in the nuclear shell model is that, to first order, each nucleon (proton or neutron) is moving in an independent way in an average field. This is not so, a priori, since the nucleus constitutes an A-body problem interacting via the nucleon-nucleon force in the ...

The nuclear shell model - of nucleons or quarks? 来自 mendeley.com 喜欢 0 阅读量: 12 作者: I Talmi 摘要: A nuclear shell model of independent quarks is critically examined. Differences between the quark shell model and the conventional shell model are pointed out. The uncorrelated quark ...

The nature of the general two-particle interaction which is compatible with symplectic symmetry in the jj coupling shell model is investigated. The essential result is that, to within an additive constant and an additive multiple of T 2, the interaction should have the form of a sum of scalar...

For A ≤ 4 nuclei, we use the no-core shell model in Jacobi coordinates61 and eigenvector continuation emulators28. The associated method and emulator errors are very small. Probabilistic attributes of the model discrepancy terms are assigned based on the expected EFT convergence pattern62,63...
Hypernuclear no-core shell model We extend the no-core shell model (NCSM) methodology to incorporate strangeness degrees of freedom and apply it to single-Lambda hypernuclei. After discussing the transformation of the hyperon-nucleon (YN) interaction into the harmonic-o... R Wirth,D Gazda,P ...
Shell modelLevel densityMonte Carlo models150 While the shell model Monte Carlo approach has been successful in the microscopic calculation of nuclear state densities, it has been difficult to calculate accurately state densities of odd-even heavy nuclei. This is because the projection on an odd ...
Basing on the nuclear shell-model and concentrating on the monopole,pairing and quadrupole corrections originating from the nucleon-nucleon force,both the appearance of low-lying O intruder states near major closed shells(Z=50,82)and sub-shell regions (Z=40,64) can be described.Moreover,a numb...
