ARTCC radar controller climbed a commuter aircraft too close to a holding pattern on the approach to mtc that had a flight of 2 F16's in it. Less than standard separation occurred. Reporter indicates frequency congestion and traffic volume as contributing factors.

Narrative:
BE02 was on a 90 degree heading to miss traffic climbing off dtw. I then gave the BE02 a climb to 13000 ft and heading to start back on course. Meanwhile I had approved an F16 flight to climb to 12000 ft and do a TACAN approach into mtc. Due to congestion and numerous aircraft on frequency, most climbing or descending, I allowed the BE02 to come too close to the vipor holding pattern of the F16 flight.
Original NASA ASRS Text
Title: ARTCC RADAR CTLR CLBED A COMMUTER ACFT TOO CLOSE TO A HOLDING PATTERN ON THE APCH TO MTC THAT HAD A FLT OF 2 F16'S IN IT. LTSS OCCURRED. RPTR INDICATES FREQ CONGESTION AND TFC VOLUME AS CONTRIBUTING FACTORS.
Narrative: BE02 WAS ON A 90 DEG HDG TO MISS TFC CLBING OFF DTW. I THEN GAVE THE BE02 A CLB TO 13000 FT AND HDG TO START BACK ON COURSE. MEANWHILE I HAD APPROVED AN F16 FLT TO CLB TO 12000 FT AND DO A TACAN APCH INTO MTC. DUE TO CONGESTION AND NUMEROUS ACFT ON FREQ, MOST CLBING OR DSNDING, I ALLOWED THE BE02 TO COME TOO CLOSE TO THE VIPOR HOLDING PATTERN OF THE F16 FLT.
