Nuclear physics

1 Introduction 1.1 A Brief History of Early Nuclear Physics In the early 1900s it was seen that a small number of alpha particles were deflected by a large angle, the current model at the time predicted only small deflections of the particles. These results were explained by introducing a tiny positively charged nucleus into our picture of the atom. Although beta decay had been observed as early as 1896 and was known to contain electrons, it wasn’t until 1914 that they would break the law of energy

Nuclear physics in the society development Nuclear physics is the field of physics that studies atomic nuclei and their constituents and interactions. The most commonly known application of nuclear physics is nuclear power generation, but the research has led to applications in many fields, including nuclear medicine and magnetic resonance imaging, nuclear weapons, ion implantation in materials engineering, and radiocarbon dating in geology and archaeology. Nuclear physics has a lot of importance

Nuclear Weapons and their Linkage with Physics The functioning of nuclear weapons requires understanding the underlying physics beginning with the structure of the atom. The nucleus of the atom consists of electrically neutral particles called neutrons and positively charged particles called protons. The no. of protons equals the no. of electrons rendering the atom electrically neutral. The nucleus of the radioactive particle U-235 has 92 protons and 143 neutrons and heavier atoms have larger

A scientist suspects that if he or she continues to research nuclear physics, his or her country will use the findings to produce a weapon capable of annihilating thousands or even millions of innocent civilians. The scientist, however, strongly believes that a weapon of this magnitude should remain nonexistent. Should he or she continue with this research even though it could be used to create a weapon of mass destruction? The scientist absolutely should. A scientist has no moral obligations in

A pellet of nuclear fuel weighs roughly 0.1 ounces, but yet has the same amount of energy as a ton of coal (McLeish, 2008, p. 47). Such a small portion of nuclear fuel can produce a magnificent impact. This strong energy alternative must be closely analyzed to predict the future of its ability. There are many characteristics that must be taken into account to permit a nuclear power plant to operate properly. The process of generating electrical power consists of several precise steps that must

report outlines the physics concepts and principles behind nuclear Fusion, the advantages and disadvantages of fusion and whether nuclear fusion could be used in New Zealand. Also, this report outlines the comparison between Fusion and Fission. A fusion is when a reaction in light nuclei combines to form a nucleus with greater mass. Fusion can take place only under extremely high temperature conditions. Another name for this process is thermonuclear reaction. The process of nuclear fusion is important

Introduction Nuclear magnetic resonance (NMR) spectroscopy and imaging are very useful tools that have practical applications for several different fields. Chemists can use NMR spectroscopy to determine the structure and composition of organic molecules. NMR imaging is used in the field of medicine to view detailed cross-sectional slices of the human body. NMR is used by the petroleum industry as well as the pharmaceutical industry. This report examines how NMR spectroscopy is used to determine the

Nagasaki in Japan, and over 200,000 people were killed immediately (ctbot.org, 2013). The principle of atomic bomb is based on the nuclear fission, which is the process that generates huge amount of energy. The modern development of nuclear technology enables fission weapons to be more powerful with a smaller size, and much easier to deliver than earlier types. However, the nuclear radiation produced by fission weapons are highly radioactive and long-lived. This would negative impact humans and the environment

Maraging steels of different compositions have been prepared by means of induction furnace electro slag remelting technique using titanium and chromium instead of cobalt which is a high expensive strategic element, also nickel content was reduced to 10-13%. Mass attenuation coefficients, half value layers and effective atomic numbers have been determined for the prepared samples at photon energies 238, 583, 661, 911, 1173, 1332 and 2614keV. The results are compared with the corresponding theoretical
