* The "Corrected Counts" column gives the true particle-gamma count emitted into the solid angles of the particle and Ge detectors. This is equivalent to the total counts for the beam run if the detectors were blackbodies (had 100% efficiency), or if the raw counts were corrected for the absolute p-gamma efficiency. | * The "Corrected Counts" column gives the true particle-gamma count emitted into the solid angles of the particle and Ge detectors.
