Monochromatic nuclear photon scattering experiment

Nuclear Instruments and Methods, 1981
Abstract A facility for the measurement of absolute cross sections and angular distributions of photons scattered elastically from nuclei has been set up in the Mainz Linac Laboratory. Quasimonoenergetic photons of 8–100 MeV are produced by the method of the positron annihilation in flight. The scattered photons can simultaneously be detected in four

Experiments in Nuclear Astrophysics

Nuclear Physics A, 2007
Astrophysics is a rapidly growing field, driven by observations from ground and space-based telescopes, which cover all wavelengths, from radio waves to ultra-high energy gamma rays. Nuclear physics experiments provide critical input parameters, which are important for the interpretation of the observational data.

Against Nuclear Weapon Experiments and Nuclear Balance

2001
Thanks to his moral integrity Otto Hahn was trusted everywhere. He used it to point uncompromisingly to three important goals. For him the cessation of nuclear weapon tests, not transferring atomic weapons in order not to let the number of atomic powers become larger, and general disarmament were the essential challenges.

Nuclear Potential Barriers: Experiment and Theory

Physical Review, 1935
The heights of nuclear potential barriers are derived from experimental data, corrected for nuclear motion and penetration through the barrier. Barriers differ markedly for different incident particles. It is shown that the heights of barriers to alpha-particles increase with atomic number and that the nuclear radius at the top is proportional to the ...

Nuclear power plant commissioning experience

Progress in Nuclear Energy, 2011
Abstract In this paper, we present the results of the analysis of the events related to the commissioning of new nuclear power plants and reported to the IAEA International Reporting System database. These results are extracted from a study performed by the European Clearinghouse on Nuclear Power Plant Operational Feedback about the events related to

NUCLEAR ASTROPHYSICS EXPERIMENTS AT CIAE

Exotic Nuclei and Nuclear/Particle Astrophysics, 2006
This paper describes the nuclear astrophysical studies using the unstable ion beam facility, GIRAFFE.We measured the angular distributions for some low energy reactions, such as 7Be(d,n)8B, 11C(d,n)12N, 8Li(d,n)9Be, 8Li(d,p)9Li and 17F(d,n)18Ne in inverse kinematics, and derived the astrophysical S‐factors or reaction rates of 7Be(p,γ)8B, 11C(p,γ)12N ...

Activation Experiments for Nuclear Astrophysics

AIP Conference Proceedings, 2009
The study of (γ,n) reactions can be used to constrain the theoretical predictions of the neutron capture cross sections of short‐lived branching points in the s process. The usability of the activation technique to study these (γ,n) reactions is discussed as one example of an activation experiment in nuclear astrophysics.

Lessons from UK nuclear experience

Power Engineering Journal, 2002
It is now 50 years since the decision was made to embark on the programme to build the world's first commercial-scale nuclear power station at Calder Hall. With the UK Government's current Energy Policy Review in full swing, the energy profile for the next 50 years is being mapped.

30. Nuclear Counting Experiments

1969
Publisher Summary This chapter discusses the nuclear counting experiments. The chapter focuses on the intensity, background, and resolution of nuclear counting experiments. It may be advantageous to sacrifice useful particles if a sufficiently large decrease of background is achieved.

Experiments with Radioactive Nuclear Beams for Nuclear Structure

AIP Conference Proceedings, 2002
Radioactive Nuclear Beams (RNBs) are opening new regions of the nuclear landscape to nuclear structure studies. Early experiments with RNBs rely on reactions with large cross sections, inverse kinematics, and very efficient detector geometries in order to measure observables that are very sensitive to structural features.
