ich habe mir ein Atommodel gebastelt, bei diesem soll der "gewellte" Pfeil mit etwas Abstand vom node k1 starten. Habe schon mit near start und (level)distance herumprobiert. Leider ohne Erfolg. Hier mein Code:
\documentclass[a4paper]{scrartcl} \usepackage[ngerman]{babel} \usepackage{tikz} \usetikzlibrary{decorations.pathmorphing,decorations.markings} \begin{document} \begin{tikzpicture}[>=latex] %Kern \node at (0,0) [shape=circle,ball color=gray!20](kern){+}; %K-Schale \draw[postaction=decorate,decoration={markings, mark=at position .25 with {\node[shape=circle,ball color=gray!20](k1){-};}, mark=at position .6 with {\node[shape=circle,ball color=gray!20](k2){-};} }](0,0)circle(1cm); %L-Schale \draw[postaction=decorate,decoration={markings, mark=at position .2 with {\node[shape=circle,ball color=gray!20](hub){-};}, mark=at position .05 with {\node[shape=circle,ball color=gray!20](l1){-};}, mark=at position .45 with {\node[shape=circle,ball color=gray!20](l2){-};}, mark=at position .7 with {\node[shape=circle,ball color=gray!20](l3){-};}, mark=at position .9 with {\node[shape=circle,ball color=gray!20](l4){-};} }](0,0)circle(2cm); %freies Elektron \node at (-3,2)[shape=circle,ball color=gray!20](e){-}; %Pfeile \draw[->](e)--(k1)node[midway,above,sloped]{$\vec{F}$}; \draw[->](k1)to[bend left](hub); \draw[->](hub)to[bend left](k1); \draw[->,decorate,decoration={snake,amplitude=.4mm,segment length=3mm,post length=3mm},thick](k1)--(3,1.5)node[midway,above,sloped]{$W=h\cdot f$}; \end{tikzpicture} \end{document}
