/* '13' To measure de-excitation gamma-rays energy (resolution
was typically 9.1% (FWHM) for the 662 keV gamma-ray as
measured with the 137Cs source), Around 90% at laboratory
scattering angles of less than 3.0 degrees, while it gradually
decreases to about 30% at 6.0 degrees. The total photo-peak
efficiency was calculated to be 23.9% for a 656 keV gamma-ray
emitted from a 34Mg nucleus in flight. The energy and
efficiency calibrations of each NaI(Tl) detector were made by
using standard 22Na, 60Co, 88Y, and 137Cs sources. */
