Least Squares Fitting

The decay of 14.9-minute 89Rb to levels in 89Sr has been studied by use of Ge(Li) detectors, NaI(Tl) detectors, and a magnetic beta-ray spectrometer. Fourteen gamma rays have been studied by γ−γ and β−γ coincidence experiments and establish levels at 0, 1.031, 2.000, 2.277, 2.567, 2.708, 2.770, 3.225, and 3.500 MeV. The Q value is 4.486 ± 0.012 MeV. The γ−γ and β−γ data were analyzed by a nonlinear least-squares fitting technique, which is described.
