Shaban, Aziz Mahmoud (1980) Investigation of the low lying energy levels in <super>56</super>Fe, <super> 75</super>As and <super>156</super>Gd with a dual-parameter energy time spectrometer.
Full text access: Open
The gamma-ray transitions from the states populated in 56Fe, 75As and 156Gd by the decay of 56Co, 75Se and 156Eu were investigated using six Ge(Li) detectors and an intrinsic Ge detector.
Coincidence studies were undertaken with a Dual-Parameter Energy-Time Spectrometer employing a fast-plastic scintillator detector and two large volume Ge(Li) detectors.
The energies and intensities of measured gamma-rays were determined. The lifetime of energy levels in the n sec. range belonging to 75As and 156Gd were measured. The level schemes were constructed; log ft values, transition multipolarities, spins and parities were deduced. Different shell-model calculations were discussed and compared with experimental results.
