    Undergrad Azimuthal direction vector notation

    First I'd like to thank you for the reply. English is not my native language. So I cannot understand what is meaning 'condescending' or not:) The definition I knew: the azimuth of a point is the angle between the positive x-axis and the projection of the vector onto the xy-plane (the component...

    Undergrad Azimuthal direction vector notation

    Thanks nasu for your reply. The x-axis in the figure which I'd sent before is the azimuthal angle. I'm posting another figure related the first one I'd sent before: http://img13.imageshack.us/img13/7756/azim2.png What should I understand from these figures? It's not the miller indices I think...

    Undergrad Azimuthal direction vector notation

    The graphic I'd sent is an azimuthal ICISS (impact collision ion scattering spectroscopy) scan of a fcc (111) lattice. Help me please...

    Undergrad Azimuthal direction vector notation

    Hello everyone! I am trying to do a literature search about ion scattering spectroscopy experiments. But I am not good at the vector notation which is used in these articles. I mean the notations with square brackets like [11-2] or [1-10] etc. (-2: the bar is on 2). For instance in a graph like...
