Beam-target interaction
in The Physics of Inertial Fusion
June 2004; published online January 2008.
Chapter. Subjects: nuclear physics. 15159 words.
Targets for inertial fusion are driven by external beams. Energy deposition of high-power laser and ion beams is considered for cold and hot dense matter. Collisional and resonance absorption of...
BROADENING OF SPECTRAL LINES
in Plasma Spectroscopy
June 2004; published online September 2007.
Chapter. Subjects: nuclear physics. 8778 words.
The Doppler broadening, the natural broadening, and the quasi-static broadening are introduced. The last broadening is due to the Stark effect in the Holtsmark micro-field with the Debye shielding....
COLLECTIVE EXCITATIONS IN EVEN–EVEN NUCLEI: VIBRATIONAL AND ROTATIONAL MOTION
in Nuclear Structure from a Simple Perspective
March 2001; published online January 2010.
Chapter. Subjects: nuclear physics. 46758 words.
The shell model is generally considered the fundamental nuclear model and works best for light nuclei. More fundamental to the shell model's central position in nuclear physics is that it provides a...
CONTINUUM RADIATION
in Plasma Spectroscopy
June 2004; published online September 2007.
Chapter. Subjects: nuclear physics. 3173 words.
The intensity distribution of the recombination continuum continues smoothly across the ionization limit to the series lines, the upper levels of which are in LTE. Thus, a Boltzmann plot of the...
THE DEFORMED SHELL MODEL OR NILSSON MODEL
in Nuclear Structure from a Simple Perspective
March 2001; published online January 2010.
Chapter. Subjects: nuclear physics. 10952 words.
This chapter describes the basic single-particle model applicable to nearly all deformed nuclei — the Nilsson model. This model is one of the most successful nuclear models ever developed, accounting...
DENSE PLASMA
in Plasma Spectroscopy
June 2004; published online September 2007.
Chapter. Subjects: nuclear physics. 8942 words.
When the plasma density is high, the Coulomb potential for the atomic electron is modified and level energies, transition probabilities are accordingly modified. Collision cross sections are also...
