Narrative:

This incident occurred on a flight from den to bur. We were in our descent, with the first officer flying, and were told to cross 5 mi east of pmd at 12000 ft and 10 mi west of pmd at 8000 ft. The east crossing restr was changed 2 times and we were also held at 17000 ft for a while. The autoplt/autoplt system was on. I turned ATC radio communications over to the first officer while attempted to get the bur ATIS. While I was on the ATIS frequency, I heard the first officer say to ATC that, 'we do not have the traffic in sight.' at this time she was looking out the window slightly to the right. I looked out for the traffic and also selected 240 KTS on the MCP, since we needed to slow before leaving 10000 ft. Shortly afterwards a light aircraft came into view and went right over our heads, slightly right. It was going in a southwest direction. The first officer pushed forward on the yoke, but it probably had no time to change our flight path before we were past the other aircraft. Shortly afterwards the other aircraft came on edwards' frequency and reported the near miss. The controller told him that we had reported him in sight. I corrected that statement, and told the controller that we had not called the traffic in sight. After landing at bur I called edwards approach and talked to the supervisor. He was aware of a near miss, but was told that it was between 2 VFR aircraft. He said he would look into the situation. Callback conversation with reporter revealed the following: report was filed with company and during their investigation determined the flight crew had advised they did not have the traffic in sight. No further information from the approach controller. Miss was approximately 100 ft and the aircraft just off the left side. Idented as a high wing small aircraft.
