Narrative:

On tomsn two arrival to the denver international airport, between tomsn and scale intxns. Told by approach to descend from 11000 ft to 6000 ft. Just prior to passing 7000 ft (approximately 7200 ft) was told to level at 7000 ft for traffic. (Jump aircraft at 7000 ft.) just as we leveled at 7000 ft we got a TCASII to descend (RA) we had to go to approximately 6600 ft to get a 'clear of conflict' message from TCASII. Never saw the offending aircraft. Remainder of the flight was normal.
