Sketch expected gamma-ray spectrum by assuming photon energy

Reference no: EM13536583

A liquid hydrogen target of the thickness of 1cm and density of 0.071 g/cm3 is bombarded with a rare isotope beam of 60Ca with an intensity of 100 counts per second. The reaction p(60Ca,60Ca(2+))p’ is observed by detecting the photons from the decay of the excited state (2+) in 60Ca.

(a) Calculate the number of photons to be observed in one week. Assume the reaction cross section of 20mb and the gamma-ray detection
efficiency of 10%.

(b) Sketch an expected gamma-ray spectrum by assuming the photon energy from the 2+ state is 4 MeV.
