more space between systems?

[Stefan Vollmar]

Dear all,

I am currently arranging a vocal piece for two voices, both voices should be in 
one system, lyrics of voice "first" should go above, of voice "second" below 
the staff:

\score {
 \new Staff = "main" <<
    \new Voice = "first" { \voiceOne \bassOne }
    \new Lyrics \with { alignAboveContext = main }
        \lyricsto "first" \bassOneL   
    
    \new Voice = "second" { \voiceTwo \bassTwo }
    \new Lyrics \with { alignBelowContext = main }
        \lyricsto "second" \bassTwoL    
    >>
}

This is already useful, however, the lyrics of the second voice are much too 
close to the lyrics of the first voice in the next system, so I would like to 
increase the white space between each system.

I have tried

\paper{
  between-system-space = 30\mm
  between-system-padding = 10\mm
}

for different sizes but this does not seem to make a difference in my case 
(lilypond 2.13.35). I have attached a small screenshot: I have put red lines 
where I need more vertical space.

Many thanks in advance for any help!
Warm regards,
 Stefan
