Topic: Binding energy per nucleon

	Binding energy - Wikipedia, the free encyclopedia
		At the nuclear level, the nuclear binding energy is derived from the strong nuclear force and is the energy required to disassemble a nucleus into free unbound neutrons and protons.
		At the atomic level, the binding energy of the atom is derived from electromagnetic interaction and is the energy required to disassemble an atom into free electrons and a nucleus.
		The region of increasing binding energy is followed by a region of relative stability (saturation) in the sequence from magnesium through xenon.

	Binding energy
		The neutron and proton binding energies are the energies necessary to release a neutron or proton from the nucleus.
		However in the case of the heaviest nuclei of an atom, such as uranium, the binding energy per nucleon is slightly less negative than for nuclei with medium mass numbers.
		Similarly the binding energy of the light nuclei of the hydrogen isotopes deuterium and tritium is significantly less negative than that of the helium nucleus He-4.

		Atomic nuclei are composed of protons and neutrons (or nucleons).
		The binding energy, Q(Z,N), of a nucleus composed of Z protons and N neutrons is:
		This is the energy needed to remove an average nucleon from the nucleus and is proportional to the fractional loss of mass when the compound nucleus is formed.

	Binding Energy (Site not responding. Last check: 2007-10-24)
		The nuclear binding energies are on the order of a million times greater than the electron binding energies of atoms.
		As the repulsive forces are increasing, less energy must be supplied, on the average, to remove a nucleon from the nucleus.
		Though fission energy seems higher, the release of energy per unit mass of the fuel, is much higher in the case of fusion than in fission.

		Uranium-235 fissions with thermal neutrons because the binding energy released by the absorption of a neutron is greater than the critical energy for fission.
		The binding energy released by uranium-238 absorbing a neutron is less than the critical energy, so additional kinetic energy must be possessed by the neutron for fission to be possible.

	Introduction (Site not responding. Last check: 2007-10-24)
		The shape of the binding energy per nucleon curve, and the fact that the nuclear density is almost constant, indicate that the nuclear force saturates.
		In the nucleus, the potential is generated by the nucleons themselves, and a good first-order approximation for the nuclear potential is a central or spherically symmetric one.
		However, as the number of valence nucleons (number of nucleons beyond a closed shell) is increased, the residual interactions between the valence nucleons that cannot be described by the mean field approximation, mean that the shell model calculations become intractable.

	Binding energy
		The binding energy B of a nucleus consisting of Z protons and N=A-Z neutrons is defined implicitly in the atomic mass
		The binding energy per nucleon B(A,Z)/A for 342 beta-stable nuclei from the 1993 mass tabulation is plotted as a function of A in Figure
		The binding energy for massive nuclei (A;SPMgt;60) thus grows roughly as A; if the nuclear force were long range, one would expect a variation in proportion to the number of possible pairs of nucleons, i.e.

	Nuclear Binding Energy
		The binding energy curve is obtained by dividing the total nuclear binding energy by the number of nucleons.
		The fact that there is a peak in the binding energy curve in the region of stability near iron means that either the breakup of heavier nuclei (fission) or the combining of lighter nuclei (fusion) will yield nuclei which are more tightly bound (less mass per nucleon).
		The binding energies of nucleons are in the range of millions of electron volts compared to tens of eV for atomic electrons.

		C, and (3) rather small binding energy of the ``last'' nucleon for nuclei with one particle above even-even, rising to considerably larger values for the last nucleon as the next even-even nucleus is approached.

	Nuclear Binding Energies
		Thus, to compute the nuclear binding energy of a nucleus with a finite number of nucleons, a correction must be made for this effect.
		This contributes negatively to the nuclear binding energy in proportion to the surface area of the nucleus, which scales as the number of nucleons to the two-thirds power.
		Since the electrostatic force is a long range force, the (negative) contribution to the binding energy of the nucleus goes as the square of the number of protons divided by the radius of the nucleus.

	The Curve of Binding Energy (Site not responding. Last check: 2007-10-24)
		The nucleon number is the sum of the number of neutrons plus protons in a nucleus; thus, it is equal to the atomic mass number) as a function of the atomic mass number A. The energy units are MeV, which stands for "million electron-volts", a standard unit of energy in nuclear physics.
		From the curve of binding energy, the heaviest nuclei are less stable than the nuclei near A=60.
		The curve of binding energy suggests a second way in which energy could be released in nuclear reactions.

	Topic 11 (Site not responding. Last check: 2007-10-24)
		The binding energy is defined as the energy released when a nucleus is assembled from its constituent nucleons.
		If we know the binding energy in a nucleus, and the number of nucleons, we can work out the binding energy per nucleon, which is the average energy needed to remove each nucleon.
		The explanation for this observation lies in that the strong nuclear force that binds the nucleus together has a very limited range, and there is a limit to the number of nucleons that can be crammed into a particular space.

		The term BE/c2 is the total binding energy** of the nucleus, expressed in units of mass.
		When the total binding energy is expressed in terms of mass such as this, it is known as the Mass Defect or Mass Deficit.
		Since the atomic mass unit mu is defined in terms of the 1/12 of the mass of the C-12 atom, it is useful to compare a particular nucleus' binding energy to that of C-12.

		The actual binding energy is not as important as the average binding energy per nucleon.
		The average binding energy per nucleon is just the total binding energy divided by the number of nucleons.
		The average binding energy is used because each nucleon actually brought into a nucleus a different binding energy.
