[Tex/LaTex] typesetting a wider bar sign


How can I make a little wider bar ?! Is that possible without defining any new commands ?
Here is a screenshot of the entry on which I want to typeset a wider bar.

You can use Hendrik Vogt's code in his answer to a similar question, or use the \widebar command from mathabx.

Here is a way to use it without having to load the package:

    \documentclass[12pt, a4paper]{article}

      <5> <6> <7> <8> <9> <10>
      <10.95> <12> <14.4> <17.28> <20.74> <24.88>


 \[ \overline{a_{ij}a_{jk}}\quad \widebar{a_{ij}a_{jk}} \]

 \[ \overline{A_{ij}}\quad \widebar{A_{ij}} \]
