Reclaim memory occupied by Table in recyclebin(dropped without purging )

Question

Hi all,
In my oracle 11g R2 database, one table 'TEST' with 3 GB size has been dropped without purge option.
So now its showing in recyclebin.
Then later i issued '*PURGE RECYCLEBIN*', so that it disppeard from recyclebin view.
But dba_segments shows the table as '[email protected]==$0' exists in the data file.
How to remove this table from the data file , so to get back 3GB size?
