WASHINGTON, July 15 - Prosecutors in the C.I.A. leak case have shown intense interest in a 2003 State Department memorandum that explained how a former diplomat came to be dispatched on an intelligence-gathering mission and the role of his wife, a C.I.A. officer, in the trip, people who have been officially briefed on the case said.

Investigators in the case have been trying to learn whether officials at the White House and elsewhere in the administration learned of the C.I.A. officer's identity from the memorandum. They are seeking to determine if any officials then passed the name along to journalists and if officials were truthful in testifying about whether they had read the memo, the people who have been briefed said, asking not to be named because the special prosecutor heading the investigation had requested that no one discuss the case.
