The Shell model was originally aimed at relating quantitative measurements of knock in engines to the autoignition properties of fuels as studied in a rapid compression machine.
By simultaneously solving the Shell model species conservation equations and the energy equation, the time evolution of temperature can be determined and thus the homogenous ignition delay predicted by the optimized Shell mechanism.
The peak temperature of the Shell mechanism is lower than that of the 4-step mechanism, but this characteristic is tuneable in the Shell model through the [gamma] parameter.
Studies of the evolution of nuclear structure in mass regions away from the valley of stability have revealed dramatic modifications of the ordering of single-particle orbitals in exotic nuclei as compared to the ones predicted by the Shell Model
A study of the shape transition from spherical to axially deformed nuclei in the even Ce isotopes has been done in  using the nucleon-pair approximation of the shell model
Washington, June 21 ( ANI ): According to the shell model
of nuclear physics, 50 is a "magic number" that gives rise to special properties.
Among their topics are elements of nuclear structure, the algebraic collective model, the shell model
, mean-field approximations, and time-dependent mean-field theory.
Most of the 26 papers are devoted to nuclear structure models and their derivation from the basic nucleon-nucleon interaction, in particular the shell model
, the interacting boson model, and the cluster model.
The model is an extension of the shell model of Arefmanesh et al.
We proceed by first describing the shell model formulation and then the formulation of the diffusion-out problem.
The bubble growth dynamics subsequent to nucleation resulting from supersaturation of a polymer-dissolved gas system have been modeled by using the shell model of Arefmanesh et al.
Bringing together writings by an international group of researchers working in different areas of quantum physics, the proceedings includes such topics as universality in few-body systems with large scattering length, simulations of dilute Fermi gases, normal persistent currents and gross shell structure in high spin, geometric aspects of the shell model
, and quantum phase transitions in two-fluid systems.
