60-inch cyclotron deuteron beam 3 sec 16.5 MEV, October 5, 1939. Cooksey 62. Cooksey notation: "Resonance was first obtained on April 17, 1939. On May 17 we had a proton beam, and on June 7 we had a deuteron beam in excesso f 17 M.E.V. The photograph shows a 16 M.E.V. deuteron beam extending five feet through the air from the 60-inch cyclotron target chamber." [Photographer: Donald Cooksey]

Bubble Chamber Event. Resonances last typically for a mere 10(-23 power) seconds and therefore leave no discernible track in a bubble chamber. But by calculating back from the energies and angles of the particles that are detected, physicists can infer that a resonance has existed. In this picture from a bubble chamber at Berkley, an antiproton, coming from below, annihilates with a proton to produces two negative pions, a neutral pion and two positive pions. The negative pions move off to the left, the positive pions to the right, while the pi-zero is undetected. The lower pi-plus decays to a muon, the short piece of track, and then to a positron, which curls out of the picture. The information in the picture is consistent with the lower-energy pions, the lower tracks on left and right-being the decay products of a resonance state known as the omega. Image not dated.

NARA & DVIDS Public Domain Archive

The objects in this collection are from The U.S. National Archives and Defense Visual Information Distribution Service. The U.S. National Archives and Records Administration (NARA) was established in 1934 by President Franklin Roosevelt. NARA keeps those Federal records that are judged to have continuing value—about 2 to 5 percent of those generated in any given year. There are approximately 10 billion pages of textual records; 12 million maps, charts, and architectural and engineering drawings; 25 million still photographs and graphics; 24 million aerial photographs; 300,000 reels of motion picture film; 400,000 video and sound recordings; and 133 terabytes of electronic data. The Defense Visual Information Distribution Service provides a connection between world media and the American military personnel serving at home and abroad. All of these materials are preserved because they are important to the workings of Government, have long-term research worth, or provide information of value to citizens.
