Change line space in a list

[Ramón Flores d'as Seixas]

Hello:

Is it an easy way to modify the line space in a list (enumerate or itemize
enviroment) ?

When using an enumerate enviroment  I obtain something like:

  1. Item one

  2. Item two

  3. Item three


But I want  the lines be separated with single space, something like:

  1. Item one
  2. Item two
  3. Item three


Thanks
