Phrase "Are you available on this Mon?'"

[Lee12jan]

Hello,

If I wanna ask someone if he/her is available on Monday or Tuesday or Wednesday,
my writing will be as following, but if there's a better way to write it as well as native.

'Are you available on this Mon or Tue or Wed ?'

[Inga]

Hello,
I think you can use this word in this meaning.
We need someone to work on this job immediately. Who's available?
someone who is available is not busy and has enough time to talk to you
Collins was not available for comment on Thursday night.
But I'm not sure of 'on this Mon or Tue'.
