lilypond book and paper

[Stefan Thomas]

Dear community,
I've seen that the paper-block in the following example, which I've used in a latex-document, has no influence on the output.
How can I get more space between the systems?

 \begin{lilypond}
                          \version "2.12.2"
                       
                                        \paper {

                                          between-system-padding = 120 \mm

                                        }
                           \relative { c4 d e f \break g1 } 
                                        \end {lilypond}
