		The design of a nuclear weapon is more complicated than it might seem - it is quite difficult to ensure that such a chain reaction consumes a significant fraction of the fuel before the device flies apart.
		Nuclear ships were built, primarily aircraft carriers, although a few icebreakers were built.
		Most natural nuclear reactions fall under the heading of radioactive decay, where a nucleus is unstable and decays after a random interval.

	Nuclear Spin
		Associated with each nuclear spin is a magnetic moment which is associated with the angular momentum of the nucleus.
		It is common practice to express these magnetic moments in terms of the nuclear spin in a manner parallel to the treatment of the magnetic moments of electron spin and electron orbital angular momentum.
		This approximate symmetry was used in trial models of the magnetic moment, and in retrospect is taken as an indication of the internal structure of quarks in the standard model of the proton and neutron.

		Nuclear spin angular momentum is quantized (as is all angular momentum) and restricted to integral or half integral values.
		In this experiment the nuclear spins are excited by a short burst of light (radiofrequency) and the resultant excited states produce a magnetic field which is detected (the Free induction decay).
		20 describes the motion of a single nuclear spin in the rotating co-ordinate frame under the influence of the static magnetic field.

		The calculation of the volume properties of the nucleus is obviously dependent on the assumed nuclear shape and on the variation of the density function over this volume.
		Method 1: Alpha particle scattering samples the onset of the strong nuclear force at which point one identifies the perimeter of the nuclear matter.
		You should be able to show that these results lead directly to the statement that, evidently nuclear matter appears to have a relatively constant density independent of A, even when A changes by over two orders of magnitude, i.e., the nucleus does not significantly compress as A increases.

	Nuclear Magnetic Resonance (NMR) (Site not responding. Last check: 2007-10-27)
		The Purcell group's method was to measure the energy absorbed by a bulk sample at resonance, while Bloch's examined the signal transferred between orthogonal coils by a bulk sample at resonance.
		This is avoided when determining the magnitude of a nuclear moment, but is utilized to determine the spin-lattice relaxation time (T_1) for a material.
		The practical uses for this phenomenon are for determining the value of nuclear magnetic moments by comparison with the proton, the measurement of magnetic fields, and most recently for medical diagnostics.

	Nuclear Magnetic Resonance
		Nuclear magnetic resonance (NMR) of protons in bulk matter was first demonstrated in 1946 independently by F. Bloch and E. Purcell who were jointly awarded the Nobel prize for their discoveries in 1952.
		The unit of nuclear magnetism analogous to the Bohr magneton of atomic physics is the nuclear magneton, µ

		Neutrons, along and many other radioactive Nuclides, nuclear weapons materials, noxious and poisonous exhaust gas products and toxic waste, and, of course, huge quantities of excess Heat, are produced in prodigious quantities, by nuclear reactors, which are widely exploited by total idiots.
		The Energy scales of nuclear reactions are wildly out of scale with, and entirely incompatible with, and severely detrimental to, the typical Energy scales of Biological Systems here on the Planet Earth.
		The entire macroscopic ensemble of Electrons, Protons and Neutrons is, in general, electrically neutral, and is subject to the techniques of Statistical Mechanics, the Laws of Thermodynamics, and, of course, Classical Mechanics and Quantum Mechanics, the combination of which, is known as Condensed Matter Physics.

		This chapter examines and compares the formulas for the Bohr and nuclear magnetons.
		The formulas for both magnetons contain the charge and mass for their respective particles.
		Clearly, the value of each magneton is a function of the wavelength of the elementary particle concerned and not of its mass as the historical formula appears to intimate.

		After Pauli's review of relativity, his main interest shifted to the quantum puzzle, to which he and his fellow student Werner Heisenberg were introduced in Arnold Sommerfeld's seminar at Munich.
		Pauli soon introduced the atomic magneton and named it after Niels Bohr.
		In 1925, before the Heisenberg and Schrödinger formulations of the new quantum mechanics, Pauli posited his famous exclusion principle, which explained the structure of atoms in conformity with the periodic table.

	Nuclear Magneton
		Concerning the Magnetic Moments of the Nucleus (Nuclear Magneton mu sub N) and the Proton (mu sub p) respectively, is the first ever measured by experiment or only defined and if so is it measured with bound electrons around it, and is the second measured for free Protons without electrons in the vicinity ?
		The nuclear magneton and proton magnetic moment has been measured by experiment, generally using magnetically guided particle beams or by submitting a sample in a tunable oscillator and measuring the Larmor precessional frequency resonance signal using an oscilloscope.
		There is no general theory of nuclear magnetism that explains this value.
