Environment - Non Weather Related; Procedure
On the SADDE arrival we were given 'cross SMO at 7;000; depart heading 070' Approaching SMO we got a 'traffic' advisory and saw an RJ ahead and well below crossing in front north bound; well de-conflicted. After we had passed; (and what I perceived as us separating) we got the red box on the PFD and a command to climb. I disconnected the autopilot; started to pitch up; and almost as soon as the RA advisory popped up; it then cleared. The whole even was maybe 2 seconds; and we resumed the descent to 7;000.
A B737 First Officer reported taking evasive action to a TCAS TRAFFIC advisory from a departing jet at 7;000 FT near SMO on the LAX SADDE STAR.
