Narrative:
Air carrier X was climbing through approximately 5700 ft when he reported receiving an 'RA.' air carrier X stopped his climb at 6200 ft MSL and passed under a traffic watch cessna, level at 6600 ft MSL. After the 2 aircraft passed air carrier X descended to 6000 ft MSL. This error occurred due to my failure to pay close attention to the traffic situation during a slow time of day.

Title: OPERROR BTWN ACR X AND ACFT Y WITH 400 FT SEPARATION WHEN ACR X STOPPED CLB AFTER TCASII RA.
Narrative: ACR X WAS CLBING THROUGH APPROX 5700 FT WHEN HE RPTED RECEIVING AN 'RA.' ACR X STOPPED HIS CLB AT 6200 FT MSL AND PASSED UNDER A TFC WATCH CESSNA, LEVEL AT 6600 FT MSL. AFTER THE 2 ACFT PASSED ACR X DSNDED TO 6000 FT MSL. THIS ERROR OCCURRED DUE TO MY FAILURE TO PAY CLOSE ATTN TO THE TFC SIT DURING A SLOW TIME OF DAY.
