Spin Flashcards
What are the possible values of the z-component of spin for an electron?
+-1/2
What is the value of the magnetic moment for an electron?
The magnetic moment for an electron is -g(rapporto giromagnetico) times the Bohr magneton times the spin angular momentum.
What is the significance of the Stern-Gerlach experiment?
The Stern-Gerlach experiment provided direct evidence for the quantization of spin, and confirmed the existence of electron spin.
What are the possible eigenvalues of Sz?
The possible eigenvalues of Sz are +1/2 and -1/2.
What is the relationship between the magnetic moment and spin of an electron?
The magnetic moment of an electron is proportional to its spin angular momentum, with a proportionality constant given by the magneton of Bohr.
What is the value of Sz in the state beta?
The z-component of spin for an electron in the state |beta> is -1/2.
What is the value of the spin quantum number for an electron?
1/2
What is the significance of the splitting of spectral lines in the spectrum of alkali atoms?
The splitting of spectral lines in the spectrum of alkali atoms is evidence for the existence of electron spin.
What is the spin of an electron?
The spin of an electron is an intrinsic angular momentum associated with the electron, which is distinct from its orbital angular momentum.
What is the relationship between the operators for spin and those for orbital angular momentum?
The operators for spin and orbital angular momentum have the same algebraic properties, but are distinct and do not commute with each other.
What is the operator for the total spin of an electron?
the operator for the total spin of an electron is S^2 = Sx^2 + Sy^2 + Sz^2.
What is the value of the total spin for an electron?
The total spin for an electron is sqrt(3)/2.
What is the magneton of Bohr?
β = eh/2mc
Cos’è la quantizzazione dello spin?
The quantization of spin refers to the fact that the orientation of an electron’s intrinsic angular momentum can only take on certain discrete values, rather than any continuous value.
