Narrative:
Departed runway 17 at iah and turned right to a 240 degree heading. Issued 12 O'clock traffic and I called it in sight. Turned further right to a 270 degree heading. Previously issued traffic was now approximately 10 O'clock. Cleared out of 4000' MSL to 6000'. Out of 5300' MSL, my first officer looked up to his right and yelled. He swung his head left and at the same time we hit wake turbulence, I saw the light transport Y jet descending in a left turn at our 9 O'clock. I estimate that he passed overhead no more than 50' vertical. By the time he was in sight off our left, he was below us. I am reluctant to place the blame on other parties normally, however we were both IFR in a radar environment. See and avoid on the part of the light transport Y pilots and the controllers would have helped. For us it was not practical.

Title: REPORTER INDICATES BOTH FLTS WERE IFR WHEN NMAC OCCURRED. 2 LTT ACFT. MISSED BY 50'.
Narrative: DEPARTED RWY 17 AT IAH AND TURNED RIGHT TO A 240 DEG HDG. ISSUED 12 O'CLOCK TFC AND I CALLED IT IN SIGHT. TURNED FURTHER RIGHT TO A 270 DEG HDG. PREVIOUSLY ISSUED TFC WAS NOW APPROX 10 O'CLOCK. CLRED OUT OF 4000' MSL TO 6000'. OUT OF 5300' MSL, MY F/O LOOKED UP TO HIS RIGHT AND YELLED. HE SWUNG HIS HEAD LEFT AND AT THE SAME TIME WE HIT WAKE TURB, I SAW THE LTT Y JET DSNDING IN A LEFT TURN AT OUR 9 O'CLOCK. I ESTIMATE THAT HE PASSED OVERHEAD NO MORE THAN 50' VERT. BY THE TIME HE WAS IN SIGHT OFF OUR LEFT, HE WAS BELOW US. I AM RELUCTANT TO PLACE THE BLAME ON OTHER PARTIES NORMALLY, HOWEVER WE WERE BOTH IFR IN A RADAR ENVIRONMENT. SEE AND AVOID ON THE PART OF THE LTT Y PLTS AND THE CTLRS WOULD HAVE HELPED. FOR US IT WAS NOT PRACTICAL.
