Non overlapping particles?

Hi all,

I’m using blender to draw in 3D some nerve portion (anatomy and physiology).
I’m using a particles system on objects (i.e axons_face.01).
I’m totally new with the particles system but is there a setting that allow particles to be nicely arranged and do not overlap?

Thanks.

A particle is just a point in space, if you display it as another object it knows nothing about the volume of the object so does not know if these representations of objects overlap each other.

I found a solution that may work:
