Narrative:

Cruising sebound shortly after crossing lhs at 9000 ft, I was startled to see a t-tailed passenger jet cross from left to right directly below us. I presumed that the traffic was on an IFR flight plan as was I. No traffic point-out was given by ATC. The visibility was about 6 mi in haze below, and much greater above us. The jet had its right wing up in a left turn, perhaps approaching burbank. The jet passed within an estimated 300 ft of us. I was readjusting mixture controls at the time, and did not see the approaching jet until my peripheral vision picked him up. He passed by so quickly that there was no time to disconnect the autoplt and take evasive action. It is unlikely that the jet was not on an IFR plan, so I don't know why ATC did not provide more separation. We had initial difficulty establishing radio contact with la after handoff from stockton approach. May be a factor. Lesson learned: keep your eyes peeled for traffic at all times. Don't rely on ATC, even when flying IFR. Keep your eyes outside the cockpit as much as humanly possible while flying the airplane.

Title: PLT OF BE35 RPTS A NMAC WITH T-TAILED JET TRANSPORT WHILE ON IFR FLT PLAN NEAR BUR. NO TA GIVEN BY SCT.

Narrative: CRUISING SEBOUND SHORTLY AFTER XING LHS AT 9000 FT, I WAS STARTLED TO SEE A T-TAILED PAX JET CROSS FROM L TO R DIRECTLY BELOW US. I PRESUMED THAT THE TFC WAS ON AN IFR FLT PLAN AS WAS I. NO TFC POINT-OUT WAS GIVEN BY ATC. THE VISIBILITY WAS ABOUT 6 MI IN HAZE BELOW, AND MUCH GREATER ABOVE US. THE JET HAD ITS R WING UP IN A L TURN, PERHAPS APCHING BURBANK. THE JET PASSED WITHIN AN ESTIMATED 300 FT OF US. I WAS READJUSTING MIXTURE CTLS AT THE TIME, AND DID NOT SEE THE APCHING JET UNTIL MY PERIPHERAL VISION PICKED HIM UP. HE PASSED BY SO QUICKLY THAT THERE WAS NO TIME TO DISCONNECT THE AUTOPLT AND TAKE EVASIVE ACTION. IT IS UNLIKELY THAT THE JET WAS NOT ON AN IFR PLAN, SO I DON'T KNOW WHY ATC DID NOT PROVIDE MORE SEPARATION. WE HAD INITIAL DIFFICULTY ESTABLISHING RADIO CONTACT WITH LA AFTER HDOF FROM STOCKTON APCH. MAY BE A FACTOR. LESSON LEARNED: KEEP YOUR EYES PEELED FOR TFC AT ALL TIMES. DON'T RELY ON ATC, EVEN WHEN FLYING IFR. KEEP YOUR EYES OUTSIDE THE COCKPIT AS MUCH AS HUMANLY POSSIBLE WHILE FLYING THE AIRPLANE.
