bohr magneton उदाहरण वाक्य
उदाहरण वाक्य
- Although the spin angular momentum of an electron is "' ", the intrinsic magnetic moment of the electron caused by its spin is still approximately one Bohr magneton.
- The magnetic dipole moment of the electron, which is much larger as a consequence of much larger charge-to-mass ratio, is usually expressed in units of the Bohr magneton.
- where is the exchange energy, the operators represent the Land?factor, is the Bohr magneton and is the internal field which includes the external field plus any " molecular " field.
- This is the basis for defining the magnetic moment units of Bohr magneton ( assuming charge-to-mass ratio of the electron ) and nuclear magneton ( assuming charge-to-mass ratio of the proton ).
- It is essentially a proportionality constant that relates the observed magnetic moment " ? " of a particle to its angular momentum quantum number and a unit of magnetic moment, usually the Bohr magneton or nuclear magneton.
- The angular momentum of an electron is either + | 2 } } or " | 2 } } due to it having a spin of, which gives a specific size of magnetic moment to the electron; the Bohr magneton.
- where \ boldsymbol { S } is the spin angular momentum vector, \ mu _ \ text { B } is the Bohr magneton and g _ \ text { s } \ approx 2 is the electron spin spin, so the magnetic moment is antiparallel to the spin angular momentum.
- where N is the number of magnetic atoms ( or molecules ) per unit volume, g is the Land?g-factor, \ mu _ B ( 9.27400915e-24 J / T or A�m 2 ) is the Bohr magneton, J is the angular momentum quantum number and k _ B is Boltzmann's constant.
- The constant A is known as the zero field hyperfine constant and is given in units of Hertz . \ mu _ B is the Bohr magneton . \ hbar \ vec J and \ hbar \ vec I are the electron and nuclear angular momentum operators . g _ J and g _ F can be found via a classical vector coupling model or a more detailed quantum mechanical calculation to be:
- The term symbol for the ground state of atomic iron is 5 D 4, so the quantum numbers are S = 2, L = 2, and J = 4 . ( S is what's usually called " the spin ", because it involves only the intrinsic spins of the electrons, but J is the total angular momentum . ) By my calculations, that makes the Land?g-factor equal to 3 / 2, so the total magnetic moment is 4 * 3 / 2 = 6 Bohr magnetons.
