Do you want something like in the attachment?
I suggest this code:

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\version "2.13.61" %didn't check it in 2.14.0. but i don't anticipate
any surprises

top = \relative c' {
 <<
   { r4
     \override  Stem #'cross-staff = ##t
     \override Stem #'length = #21
     \override Stem #'Y-offset = #-7
     \override  NoteColumn #'ignore-collision = ##t
     e e e }
   { s4
     \change Staff = "bottom"
     c, c c
   }
 >>
}

bottom = \relative c' {
 \clef bass
 \voiceOne % similar results with \voiceThree or \stemUp
 g8 a g a g a g a
}

\new PianoStaff <<
 \new Staff = "top" {
   \top
 }
 \new Staff = "bottom" {
   \bottom
 }
 >>
