Title: I need help with this quantum physics problem!
Post by: whabang on February 17, 2004, 10:40:41 AM
In case you didn't notice, this thread is meant to die!

I knew that's what it was for the moment I read it on the recent postings list :)

Great! I'm actaully rather pleased you strated the tradition :-) long may it last! :pint:


First you have to find an exact solution to the schrodinger equations for the Helium atom... eh?

Ok,
I have a feeling that this is one of those threads that will never die. Can one of you moderators move this to the DMZ, please? :-)

Oh, and BUMP!

I think you should start with the He+ ion. Since that only has one electron you can use the hydrogenic model. So you can write the hamiltonian for that.

Yeah?
What if were to use carbon and deutrim, then?
Would that mean that I have no clue what you're talking about? :-D

Deuterium is no problem since it only has one electron... with carbon you have the same problem as Helium, where electron election interactions make it imposible to work out an exact solution.

Let's stick with Dilithium, eh? ;-)

Hmmm, this subject is as elusive as unobtanium to me.

Will we use the variational theorem, or perturbation theory? In fact, I have on old Matlab program for iterating Hydrogenic wave functions using the variational method somewhere -  a relic of my university days...

Can you specify your question and do you have a source where all of us can read what it's actually all about?

Hmm...seems my topic idea for a thread you want to die didn't work. Let me suggest some others, that hopefully will make people pass them by without a read.

* Ow! Need help with piles!

* How to write a CV/Resumé

* Help! memalloc.h is missing on my Debian install!

* Amiga.org bugs

* Petition for DOOM 3 to be ported to Amiga!

* A600 on sale on eBay

* Another maths puzzle for you

* Who's next to get voted out of teen Big Brother?

* PPC rulez x86!

* OS4 vs. MOS

* OS4 - is it ready yet??? :D:D:D:D

etc.

I will try one of those next time! :)

Variational theorem, since I never learned the other one :-P
