Narrative:
Wbound on J2 over bard VOR had TCASII RA to climb for crossing traffic (unknown to center) at FL260. Started climb and advised ATC we were doing so. Stopped climb at FL268 and returned to FL260. ZLA claimed they had no traffic for us at that altitude (FL260). I never actually saw the traffic.
