Ion mobility of Isobutane in Garfield++

Hi,

I am trying to simulate a gas cell with isobutane gas using Garfield++. But I could not find the ion mobility table for Isobutane gas in the papers that I read, since the file is already not given in the downloaded files of Garfield.
Can someone suggest what to do?

This paper has a table. Is it the one you are looking for ?

Hi,
I’ve just uploaded a mobility file to the repository

using the value for C8Hn+ ions in pure isobutane, taken from the paper mentioned by @couet.

Thank you so much.
