Is there a way to prevent ugly collision of axes labels and axes number like in the following examples, without the need of adding white space:
Plot1:
Plot3D[Sin[x] Cos[y], {x, -Pi, Pi}, {y, -Pi, Pi}, AxesLabel -> {"ω", Subscript["E","F"], "Log[σ(ω)]"}, LabelStyle -> Directive[16]] 
To avoid this distant axes label "Log[$\sigma(\omega)]" one can rotate it, but then:
Plot2:
Plot3D[Sin[x]Cos[y],{x,-Pi,Pi},{y,-Pi,Pi}, AxesLabel->{"ω",Subscript["E","F"],Rotate["Log[σ(ω)]",90 Degree]}, LabelStyle->Directive[16] ] 
I cannot imagine that using a 2-dimensional column with one element "Log[σ(ω)]" and the other a blank square is the only solution to cure Plot2. Is there a nice solution to prevent such an overlay?
