Hi

Does someone know where I can get access to the following article on the internet without paying for it?

"The Period of $F = -kx^{n}$ Harmonic Motion" by Chris Hirata and David Thiessen, The Physics Teacher, December 1995, page 563

Additionally if you are aware of textbooks/internet sites which discuss this mathematically, please do let me know.

Thanks and cheers
Vivek

No.Have you checked a good LIBRARY...?Maybe paper is better than e-format...Sure,you can print it,if you have it in e-format,but a library may have free online subscription to the magazine...

Google something more specific, like "quartic potential well". Lotsa hits to that.

Thanks for your replies. Well, I tried searching this in the database of the nearest library I have access to...in vain. If you know where I can get information about this topic (and not necessarily from the same source) please do let me know.

You mean that they didn't have the collection of the magazine/journal including the issue with the article...?I assume you searched at an UNIVERSITY library...That's weird.One thing is for sure:it's definitely at the Library of Congress.So if your Quantum Corral has a nonzero probability of being in Washington,you might wanna check it out...

As for $r^{n}$ potentials and closed orbits,there's definitely a chapter and a theorem in 3-rd ed.of Goldstein...
