Short Answer

Expert verified

It is proved that symmetric and asymmetric combination are the solution of two particles Schrodinger equation.

Step by step solution

01

Given information

The symmetric wave function isψs(x1,x2)=ψn(x1)ψn(x2)+ψn(x1)ψn(x2) .

The asymmetric wave function isψA(x1,x2)=ψn(x1)ψm(x2)ψm(x1)ψn(x2) .

02

Concept of complex number:

The expression for combination of symmetric and asymmetric wave function is given by ψSA(x1,x2)=ψn(x1)ψn(x2)±ψn(x1)ψn(x2)

03

Evaluate symmetric and asymmetric wave function

The expression for combination of symmetric and asymmetric wave function is calculated as,

Apply Schrodinger wave equation

By Schrodinger wave equation in one dimension,

Considering equation (1) and (2)

h22m2x12+2x22ψSA(x1,x2)+[U(x1)+U(x2)]ψSA(x1,x2)=EψψSA(x1,x2)

Thus, the symmetric and asymmetric combination obeys the Schrodinger equation with two particle solution.

A hydrogen atom in its ground state is subjected to an external magnetic field of 1.0 T. What is the energy difference between the spin-up and spin-down states?

A hydrogen atom is subjected to a magnetic field Bstrong enough to completely overwhelm the spin-orbit coupling. Into how many levels would the 2p level split, and what would be the spacing between them?

The 21cm Line: One of the most important windows to the mysteries of the cosmos is the 21cm line. With it astronomers map hydrogen throughout the universe. An important trait is that it involves a highly forbidden transition that is, accordingly, quite long-lived. But it is also an excellent example of the coupling of angular momentum. Hydrogen's ground state has no spin-orbit interaction—forl=0there is no orbit. However, the proton and electron magnetic moments do interact. Consider the following simple model.

(a) The proton seesitself surrounded by a spherically symmetric cloud of 1s electron, which has an intrinsic magnetic dipole moment/spin that of course, has a direction. For the purpose of investigating its effect the proton, treat this dispersed magnetic moment as behaving effectively like a single loop of current whose radius isa0then find the magnetic field at the middle of the loop in terms of e,,me , μ0anda0.

(b) The proton sits right in the middle of the electron's magnetic moment. Like the electron the proton is a spin12particle, with only two possible orientations in a magnetic field. Noting however, that its spin and magnetic moment are parallel rather than opposite, would the interaction energy be lower with the proton's spin aligned or anti-aligned with that of the electron?

(c) For the protongρ.is 5.6. Obtain a rough value for the energy difference between the two orientations.

(d) What would be the wavelength of a photon that carries away this energy difference?

Two particles in a box have a total energy 5π22/2mL2.

(a) Which states are occupied?

(b) Make a sketch ofP5(x1,x2)versusx1for points along the linex2=x1.

(c) Make a similar sketch ofPA(x1,x2).

(d) Repeat parts (b) and (c) but for points on the linex2=Lx1

Compare and contrast the angular momentum and magnetic moment related to orbital motion with those that are intrinsic.
