Airspace Structure; Human Factors; Procedure
I had descended the CE560 to 14;000; per LOA for aircraft landing PSP. The Sector 19 Controller was providing RADAR advisories to a King Air; and stopped his climb VFR at or below 13;500; for my 14;000 traffic. At 6 miles out; I called traffic for the CE560; and he said; 'I think we're going to get an RA'. I have a reasonable amount of experience with TCAS equipment; from both sides of the mic; and that was a new one for me!! I guess he must have some new predictive TCAS/RA equipment that I don't know about. In any event; a few miles later; the CE560 pilot said he was conducting an RA climb. Altitude indicated 14;400 on the scope. Aircraft passed each other and I initiated a comms change to SoCal Approach; Springs Sector.
ZLA Controller describes a TCAS RA event between a CE560 descending to 14;000 FT and a King Air climbing to 13;500 FT. The CE560 pilots take evasive action climbing to 14;400 FT.
