It seems history won't rest until someone fills in that 18 1/2-minute Watergate gap.

One of the enduring mysteries from the scandal that consumed Richard Nixon's presidency is coming under renewed scrutiny from forensic scientists gathered by the National Archives.

Their mission: Use the latest technological tools to find out what Nixon and his chief of staff, H.R. Haldeman, discussed during those missing minutes on the tape recording of a June 20, 1972, meeting. The meeting came three days after the break-in at Democratic Party headquarters at the Watergate Hotel by burglars linked to the president's re-election committee.

Experts have failed to unlock mysteries from the erased tape itself over the years. Now, they are turning their attention to two pages of handwritten notes taken by Haldeman in his session with Nixon that day.

They will search for clues that incriminating pages are missing and try to reconstruct what Haldeman, a prolific note-taker on yellow legal pads, might have written on them.

The questions of what Nixon knew and when were central in the investigation of the Watergate cover-up, and it caused a sensation when special prosecutors learned of the gap in one of the recordings they had subpoenaed.

The archives said Wednesday it is convening a forensic team from the Library of Congress, the Treasury Department's inspector general's office and the Bureau of Alcohol, Tobacco, Firearms and Explosives to do the detective work. Test results are expected early in 2010.

Among the advanced tools for the task is electrostatic detection analysis. The technology is capable of detecting and highlighting indented images, such as those left on a sheet of paper when a pen has written on a sheet above it. This might show evidence that certain pages were destroyed and even point to words long lost to history.

Nixon historians are excited about the prospect of confirming that a gap exists in the notes, corresponding with the gap in the recording.

"My best scholarly guess _ and there has certainly been a lot of speculation in the past 35 years about what is on the gap _ is that Nixon asked Haldeman if anyone in the White House had advance knowledge of the Watergate break-in," said Luke A. Nichter, a Texas A&M University assistant history professor who is a leading authority on the Nixon White House recordings.

Techniques known as hyperspectral imaging and video spectral comparison also will be used to study the ink and look for hidden clues to missing material.

The first page of Haldeman's notes is routine, mostly concerning a letter to be written to the South Dakota governor.

The other page reflects Nixon's fear that the Executive Office Building office where they were meeting might be bugged.

It goes on to address Nixon's critics in the first blush of the scandal, asking, "What is our counter-attack?" and demanding a public relations "offensive to top this."

"Hit the opposition w their activities," say the notes. "We shld be on the attack _ for diversion."

The existing notes roughly correspond with portions of the tape that can be heard, historians say.

The question is whether missing notes, if any, can be gleaned from those papers and whether they will shed light on deeper secrets from that time.
