Narrative:

Coast approach handed us off to lax approach. The first officer called lax who responded 'air carrier mdt, traffic alert, traffic 12 O'clock less than a mi, opp direction indicating 6800'.' I immediately started a climbing right turn. Shortly after doing so, I spotted an oncoming small aircraft at approximately 7000'. My altitude gain was 500' with a heading change of approximately 20 degrees. In retrospect, the small aircraft would have missed us had I taken no action at all. However, not having visibility contact with the small aircraft (sho was not talking to anyone) and hearing the urgency in the controller's voice, I felt I had no choice but to take evasive action. The controller (lax 124.9) is to be commended for his quick attention to the matter.

Title: CLOSE PROX ACR-MDT GA-SMA ON AIRWAY SOUTH OF SLI.

Narrative: COAST APCH HANDED US OFF TO LAX APCH. THE F/O CALLED LAX WHO RESPONDED 'ACR MDT, TFC ALERT, TFC 12 O'CLOCK LESS THAN A MI, OPP DIRECTION INDICATING 6800'.' I IMMEDIATELY STARTED A CLBING R TURN. SHORTLY AFTER DOING SO, I SPOTTED AN ONCOMING SMA AT APPROX 7000'. MY ALT GAIN WAS 500' WITH A HDG CHANGE OF APPROX 20 DEGS. IN RETROSPECT, THE SMA WOULD HAVE MISSED US HAD I TAKEN NO ACTION AT ALL. HOWEVER, NOT HAVING VIS CONTACT WITH THE SMA (SHO WAS NOT TALKING TO ANYONE) AND HEARING THE URGENCY IN THE CTLR'S VOICE, I FELT I HAD NO CHOICE BUT TO TAKE EVASIVE ACTION. THE CTLR (LAX 124.9) IS TO BE COMMENDED FOR HIS QUICK ATTN TO THE MATTER.
