Narrative:
Working the radar east position; [I] told aircraft X to turn right to a 140 heading to avoid traffic and descend to nine thousand. I was having issues with another aircraft and my attention was on that situation. Aircraft Y was 10 miles west of elp and his altitude had been changing between 8;500 and 9;000. When I realized that aircraft X and aircraft Y had only 300 feet apart vertically and their lateral separation was diminishing I turned aircraft X to a 070 heading to avoid aircraft Y. Aircraft X said he was responding to an RA and climbed to 9;300.I think a better scan would have helped me realize the situation sooner. Also; assigning a higher altitude would have given me more control over the situation.
