Narrative:
On an unpressurized ferry flight [to] lax at a cruise altitude of 10;000 feet; got a TA on an aircraft below us 12 o'clock and climbing. At approximately 4 miles ATC gave us a traffic advisory at the same time we got an RA with a climb command. As we were climbing the first officer spotted the aircraft coming right at us and said 'turn left.' I rolled into a 35-40 degree turn as the ATC controller was advising a right turn which we could not comply with at that point. We observed we were climbing with the other aircraft with a constant 100 feet separation. The first officer still watching the other aircraft said 'descend - descend.' as I was lowering the nose the other aircraft passed behind us at close range. We climbed to approximately 11;300 feet before descending to 10;000 feet and returning on course. It appears we (both aircraft) were nearing the border between two sectors because we were not on the same frequency. Seconds before our controller had given us a frequency change; then said to stay with him and then gave us the traffic advisory as we were responding to the RA. It is not apparent to me that the other aircraft maneuvered to avoid us or even saw us. The other aircraft was a cessna citation.

Title: An MD82 Captain on an unpressurized ferry flight encountered an opposite direction Citation and responded to TA and RA warnings as well as directives from the First Officer based on visual contact.
Narrative: On an unpressurized ferry flight [to] LAX at a cruise altitude of 10;000 feet; got a TA on an aircraft below us 12 o'clock and climbing. At approximately 4 miles ATC gave us a traffic advisory at the same time we got an RA with a CLIMB command. As we were climbing the First Officer spotted the aircraft coming right at us and said 'TURN LEFT.' I rolled into a 35-40 degree turn as the ATC Controller was advising a right turn which we could not comply with at that point. We observed we were climbing with the other aircraft with a constant 100 feet separation. The First Officer still watching the other aircraft said 'DESCEND - DESCEND.' As I was lowering the nose the other aircraft passed behind us at close range. We climbed to approximately 11;300 feet before descending to 10;000 feet and returning on course.
