           (J,ZP/A,274,349,1975)
FACILITY   (REAC,2GERJUL) FRJ-2 (DIDO), 2E+08 neutrons/cm2/sec
            at the target position
SAMPLE     1.5g distilled water in a thin lucite container placed
            inside a cylindrical shield of 6LiD (7 mm thick).
METHOD     (COINC) gamma-gamma coincidence measurement with
            conventional fast-slow coincidence equipment
DETECTOR   (GELI) Ge(Li) detectors of 59 and 62cm3 used in the
            first measurement while those of 120 and 127 cm3 used
            in the third and fourth measurements.
           (NAICR) Two Nai(Tl) scintillators (10.2 cm * 10.2 cm,
            7.6 cm * 7.6 cm) in the second measurement.
           .LEAD SHIELDING BETWEEN THE DETECTORS TO SURPRESS
            CROSSTALK.
ANALYSIS   Weighted averages of the results from four measurements
CORRECTION Corrected for
           . random coincidences
           . continuous background due to compton events
           . full energy peak efficiency and solid angle
ERR-ANALYS Single standard deviations
