Does anyone have a source on degenerate matter other than wikipedia?

Homework Statement The scattering amplidtude, F, of a, by a crystal, diffracted beam is defined to be: (1) F=\sum{_\vec{G}}\int n_{\vec{G}}e^{i(\vec{G}-\delta\vec{k})\cdot \vec{r}}\mathrm{d}V The integral is over all the volumeelements, dV, of the crystal. n_{\vec{G}} is the local...

Thanks for the responds, i see it clearly now. I got confused in the different variables and also i was not proberly aware that a kinetic and potential energy is attached to each of the particles.

Homework Statement The following is a summaration of a piece of text in my textbook: The setting is two particles moving in one dimension, under mutual forces, so that the equations of motion are (1): m_1 a_1=F and m_2 a_2=-F (a stands for acceleration) F is only a function of...

Okay guys We are turning in the project today, so we can't make changes to the set up. We are asuming that the graphs was shifted compared to each other when it was meassured with the oscilloscope. The graphs was not emassured simultainously so the oscilloscope might have taken different zero...

This is a experiment I am doing with a group for a project. Our supervisore told us that maybe there can be a problem with the measureent of the current as a rms value. This is a mode on the multimeter designet for ordinary alternating current, which is not the cast here. And that maybe the...

The 2.2 Voltage (rms value) which I imentioned was measured with a multimeter over the terminals of the power supply. The current was measured also with a multimeter but ofc. in connected in series. And thank you for your guess, but the differences in current are just very big. Yer, the...

Dear forum I have s issue concerning rectification of a sinusoidal voltage with a diode. It is a experiment i am doing. The case is a 1N4001 diode in series with a lamp and a capacitor in parallel to the lamp. The circuit is supplied by a sinusoidal voltage with a rms value of 2.2 V. The...
