What version of LilyPond?
1.3.x:

    %s.fly

    a''

    % short stem
    %urg: stemLength is given in halve spaces?
    \property Voice.stemLength = #5
    a
    % long stem
    \property Voice.stemLength = #10
    a
    % normal again
    \property Voice.stemLength = ##f
    a

if you want to override the default, you can (1.3) override 'stem-length'
from scm/paper.scm:
 
    #(define stem-length '(3.5 3.5 3.5 4.5 5.0))

for 1.2, see ly/params.ly

This is still experimental.  With > 1.3.12, you can use 

    % from upper staffline to centre
    \property Voice.beamVerticalPosition = #10
    \property Voice.beamSlope = #10
