AB  - As a by-product of another measurement, ratios of the single-escape (SE) and 
      double-escape (DE) efficiencies relative to the full-energy-peak efficiency (FE) 
      have been measured for two HPGe detectors for (60)Co. For a 2.5-cm-thick 95 cm(3) 
      crystal the results were SE/FE = 0.000 48 +/- 0.000 20 and 0.003 25 +/- 0.000 24 for 
      1173 and 1332 keV gamma-rays, respectively, and DE/FE = 0.000 90 +/- 0.000 17 and 
      0.003 41 +/- 0.000 11 for 1173 and 1332 keV, respectively. For a 3.0-cm-thick 84 
      cm(3) crystal the results were SE/FE = 0.000 67 +/- 0.000 32 and 0.003 79 +/- 0.000 
      27 for 1173 and 1332 keV respectively, and DE/FE = 0.001 05 +/- 0.000 28 and 0.004 
      29 +/- 0.000 16 for 1173 and 1332 keV, respectively. These measurements may be of 
      relevance in connection with Monte Carlo calculations of HPGe detector 
      efficiencies, and may also suggest a path towards improved atomic cross-section 
      measurements.
