Hi! I have some problems using units or cite commands in combination with line breaks. Using: ... energies up to 3 \EVolt were measured .... will produce no whitespace between "eV" and "were" ... energies up to 3 eVwere measured ..... In order to get the space correct between the unit and the following word I inserted a "~" to ensure the space. But this will not force the line break between the unit and the following word when it is necessary. In that case hypphenation will be used after the first syllable. I encountered the same effect using the \cite command to reference bib-items but not to reference tables or pictures with the \in command. How can I create a space after the unit and have correct line breaking at the same time? Thanks Michael
