Understanding of interaction of γ-rays with matter: attenuation coefficient measurements

The leftover nucleus from a composite system formed by fusion of two heavy ions may remain excited after emission of particles (i.e. neutrons, protons & α), and upon de-excitation it may release gamma photons. These gamma transitions are recorded using high-resolution gamma spectrometers and which are then analysed to comment on the structure of nucleus. In the present manuscript an attempt has been made to understand the contribution of the interaction processes in attenuation coefficients for different elements such as Al, Cu, Zn, and Pb at various gamma-energies for which an experiment was performed using HPGe Clover detector and ¹³³Ba as radioactive source of γ-rays. The mass attenuation coefficient(µm) that includes the density of absorber material has been measured which is defined as ratio of linear attenuation coefficient and density of material
