Beam collision next note's accidental within single voice

[Tom Hall]

Hello list

how can I move a beamed note (the e-flat below) to the right, to avoid collision
of the accidental with the beam of the preceding note?

I've managed to lift the beams OK by overriding the beam positions, but what's
needed i think is a horizontal right shift e-flat.

I've looked at posts and LM section 4.5.2. on \override NoteColumn
#'force-hshift, but am thinking this only applies to multiple voices, as seems
to have no effect on the below. 

I imagine that this is straightforward, but am fairly new to tweaks...

Regards

Tom
