Webordering and relating these data has been the nuclear shell model (1-4). The model is easily formulated: Nucleons in a nucleus move independently of each other in an average single-particle potential. At the same time, it is difficult to derive the model from first principles. The validity of such a model can be established by constructing a ... Webgoverned by the Navier-Stokes equations. The shell models are constructed to obey the same conservation laws and symmetries as the Navier-Stokes equations. Besides …

In the case of the simplest nucleus (the deuterium, with 1p-1n) we have been able to solve the time independent Schrödinger equation from first principles and find the wavefunction and energy levels of the system —of course with some approximations, simplifying for example the potential. Webfrom the shell model gets much worse. The precise origin of the magnetic dipole moment is not understood, but in general they cannot be predicted from the shell model. For …
Webrule requires iterative screening during optimization, which means that predictors cannot be screened prior to fitting the model. This highlights the difficulty in developing screening rules for SLOPE. Our main contribution in this paper is the presentation of a first heuristic screening rule for SLOPE based on the strong rule for the lasso. Weband/or neutrons). We illustrate the advances that have been made from the early 1p-shell nuclei (1965) towards recent calculations with very big model spaces and many nucleons. In particular we show results for the sd shell and the fp shell. In the latter case, it is shown that structures reminiscent of collective modes of motion (macroscopic ...

An important characterization of electromagnetic and weak transitions in atomic nuclei are sum rules.
