Accepted ho of small aircraft X descending to 11000, landing alb. Already working small aircraft Y, on airway wbound, level at 10000 small aircraft X was issued descend and mountain 6000' anticipating descent rate and aircraft tracks to permit divergence. Attention was distracted due to a lack of a data man to perform coordination with a satellite airport. When I completed the necessary coordination and looked back at the scope I observed a potential conflict between aircraft. Still separated I issued a turn to small aircraft X, using wrong call sign. No action taken by aircraft. Then issued another turn and descent to small aircraft X including a traffic alert. Small aircraft X followed instructions. Separation was compromised due to distraction of non-control duties and then using wrong call sign. I will prevent recurrence by not allowing distraction from non-control duties and by attention to call signs.

Title: LESS THAN STANDARD SEPARATION WHEN SMA IS DESCENDED THROUGH THE ALT OF OPPOSITE DIRECTION SMA.
Narrative: ACCEPTED HO OF SMA X DESCENDING TO 11000, LNDG ALB. ALREADY WORKING SMA Y, ON AIRWAY WBOUND, LEVEL AT 10000 SMA X WAS ISSUED DESCEND AND MOUNTAIN 6000' ANTICIPATING DESCENT RATE AND ACFT TRACKS TO PERMIT DIVERGENCE. ATTN WAS DISTRACTED DUE TO A LACK OF A DATA MAN TO PERFORM COORDINATION WITH A SATELLITE ARPT. WHEN I COMPLETED THE NECESSARY COORDINATION AND LOOKED BACK AT THE SCOPE I OBSERVED A POTENTIAL CONFLICT BETWEEN ACFT. STILL SEPARATED I ISSUED A TURN TO SMA X, USING WRONG CALL SIGN. NO ACTION TAKEN BY ACFT. THEN ISSUED ANOTHER TURN AND DESCENT TO SMA X INCLUDING A TFC ALERT. SMA X FOLLOWED INSTRUCTIONS. SEPARATION WAS COMPROMISED DUE TO DISTR OF NON-CTL DUTIES AND THEN USING WRONG CALL SIGN. I WILL PREVENT RECURRENCE BY NOT ALLOWING DISTR FROM NON-CTL DUTIES AND BY ATTN TO CALL SIGNS.
