This report looks at the background of Iran's nuclear policy. It covers the current status of Iran's nuclear facilities, and current controversy surrounding them, as well as the effects of international sanctions on Iran, recent sabotages on the Iran Enrichment Program, an estimated timeline of Iran's nuclear weapon capabilities, and whether or not Iran even has a nuclear weapons program.
A laser is a unique tool to produce plasma and photon beams or particle beams with very high fluxes and very short durations. Both aspects are of interest for fundamental nuclear physics studies.
The $\alpha$-particle condensate in nuclei is a novel state described by a product state of $\alpha$'s, all with their c.o.m. in the lowest 0S orbit. We demonstrate that a typical $\alpha$-particle condensate is the Hoyle state ($E_{x}=7.65$ MeV, $0^+_2$ state in $^{12}$C), which plays a crucial role for the synthesis of $^{12}$C in the universe. The influence of antisymmentrization in the Hoyle state on the bosonic character of the $\alpha$ particle is discussed in detail. It is shown to be weak. The bosonic aspects in the Hoyle state, therefore, are predominant. It is conjectured that $\alpha$-particle condensate states also exist in heavier $n\alpha$ nuclei, like $^{16}$O, $^{20}$Ne, etc. For instance the $0^+_6$ state of $^{16}$O at $E_{x}=15.1$ MeV is identified from a theoretical analysis as being a strong candidate of a $4\alpha...
The nuclear level-density parameters obtained in the Yukawa folded potential approach are presented. The particle-number averaging ({N} averaging) Strutinsky shell-correction method is used to extract the shell-correction energy and its change with temperature and the macroscopic nuclear energy for 130 spherical even-even nuclei. A liquid-drop type expression is proposed for the level-density parameter. The best agreement is achieved between our results and the phenomenological formula of von Egidy based on a back-shifted Fermi gas model.
Recent advances on the dipole and monopole responses of the atomic nucleus are discussed. The soft dipole response is diversified and its structure depends on the nucleus. The giant dipole resonance is involved in astrophysical processes such as the r-process and in the propagation of ultra-high-energy cosmic rays. A soft monopole response is predicted. The giant monopole resonance is related to the determination of the nuclear incompressibility, but an alternative quantity may be better extracted from measurements.
This report discusses the nuclear energy policy issues facing Congress that include the implementation of federal incentives for new commercial reactors, radioactive waste management policy, research and development priorities, power plant safety and regulation, nuclear weapons proliferation, and security against terrorist attacks.
