Calculating Stark Effect for 3 States of Hydrogen

In summary, the conversation discusses the construction of a 9x9 matrix for the perturbing Hamiltonian of the Stark effect for n=3 states of hydrogen. It also mentions finding the eigenvalues and their degeneracies. The importance of showing work and relevant formulas in order to receive help is emphasized. The conversation also includes a reference to the standard given before posting in forums.

Hi Here is my question,

Consider stark effect for n=3 states of hydrogen there are nine degenerate states ?3lm(neglect spin),We turn on
an electric field in Z direction.
a)construct 9 x 9 matrix representing perturbing hamiltonian.

b)find eigen values and their degeneracies.

noone will ever help you unless you show some work and what relationships you know etc.

And why answer you at you mail?
 
  • #3
why no one will ever help me

which work do u want and what relationships you want etc.
 
  • #4
It is how things work in these forums, it is the rules that you give your work done so far, thougts, and relevant forumlas etc in order to get helt.

Thats why the standard



Is given before you write something new here.

What is the meaning of all this BS?
What is your starting point for calculating the interaction with the electric field?
What are the pedagogical aims of this exercice: just making a big calculation based on hydrogen wavefunctions, or exploring the effect of symmetries and a simple application of group theory (wigner-eckart)?
What is the context?
Are you supposed to calculate the level displacements as a function of the electric field and to compare with experimental data?
For the eigenvalues, do you mean the eigenvalue of the pertubation or of the perturbed hamiltonian?
Are you going to calculate that numerically of to calculate first order perturbation (may be this is the purpose of this exercice?).

Sorry but if you are lazy, I will be too.
This is a very nice exercice, you should spend a lot of time on that to enjoy.

hlp

dont know any thing about this topic .
i hve missed my classes due medical reasons , so don't know anything abt this topic and has to complete this question as homework
now can anybody help me
pleawse slove it ASAP

Sorry but it is not how things work in these forums, that we give away solutions just like that.

What are you sources of information for this problem? Have you asked your teacher for information?
 
  • #12
sources of information for this problemis my teacher
asked my teacher for information but she refused to help me

help ASAP

please anyone help me
i need the solution quickly , as the last date for submittion is aproching
please help me

We don't know the level of your course, or the aim of the exercice.
I told you to explain us more about that.
There are many different ways to solve this question.

A very simple and elementary way is to calculate the matrix elements directly from the n=3 wavefunctions (see there for example: http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/hydwf.html )

I assume you at least know the form of the pertubation to add to the hamiltonian!
 
  • #15
the level of my course is graduation
there is nothing about stark effect in that link
my frnd gave me this gave as hint.

the partial answer is given as <300|Z|310>=-3sqrt(6)a.
<310|Z|320|=-3sqrt(3)a.
<31(+ 0r -)1|Z|32(+0r-)1>.
=-4.5a
 
  • #16
well,
write Z explicitely,
plug the wavefunctions from the link I provided,
calculate all the needed matrix elements,
use the first order perturbation theory,
or solve exactly by numerical diagonalisation

then learn quantum mechanics to understand the meaning of your calculations

i can't understand you
please be bit clear
 

1. What is the Stark Effect?

The Stark Effect is a phenomenon in which the energy levels of an atom or molecule are shifted in the presence of an electric field. This can occur when the atom or molecule has a permanent dipole moment, or when an induced dipole moment is created by the electric field.

2. How is the Stark Effect calculated?

The Stark Effect is calculated using the formula ΔE = qF, where ΔE is the change in energy, q is the charge of the particle, and F is the strength of the electric field. This formula is used to determine the energy shift for each energy level in an atom or molecule.

3. What are the 3 states of hydrogen that are used in calculating the Stark Effect?

The 3 states of hydrogen used in calculating the Stark Effect are the ground state (n=1), the first excited state (n=2), and the second excited state (n=3). These states have different energy levels and are affected differently by an electric field.

4. How does the Stark Effect change for each state of hydrogen?

The Stark Effect changes for each state of hydrogen because the energy levels of the atom are different. The ground state has the lowest energy level and is most affected by the electric field, while the excited states have higher energy levels and are less affected by the electric field.

5. What factors can affect the calculation of the Stark Effect for hydrogen?

The factors that can affect the calculation of the Stark Effect for hydrogen include the strength of the electric field, the charge of the particle, and the energy levels of the atom. Additionally, the presence of other atoms or molecules nearby can also affect the calculation.
