Relativistic atomic beam spectroscopy. Progress report, July 20, 1987--June 30, 1989
With the HIRAB (High Resolution Atomic Beam) building, the photodetachment experiments at LAMPF was able to continue. The 1988 runs provided data to complement that of 1986 on effects of electric fields on photodetachment cross section of H{sup -} and interaction of thin foils with relativistic H{sup -} ions. The first multiphoton detachment of H{sup -} was observed. In each of these experiments, a high-powered laser beam was allowed to intersect the relativistic ion beam; the photon energy in the barycentric system is Doppler shifted, and the laser may thus effectively be tuned (through up to a decade) by changing the angle of intersection of the 2 beams.
