Problem 7 (Ch 32): 60 Co (Cobalt 60) decays through ß- decay to an excited state of 60Ni (Nickel 60). To get to the ground state, the nickel emits a 1.1732 MeV gamma ray followed by a 1.3325 MeV gamma ray. If the nickel emits those gamma rays from rest in the exact same direction, what is the final recoil velocity of the nickel nucleus? The mass of 60Ni is 59.930786u. (10 points)

Technetium Dosage. Radioactive isotopes are often used for medical imaging. Technetium-99m (Tc-99m) is a particularly popular isotope since it has a short half-life and is easy to make. Also, Tc-99m can be chemically bonded to a number of different compounds and cell types for imaging different parts of the body. Tc-99m has a half-life of 6.02 hours. It decays into Tc-99 by emitting a gamma ray of energy 140 keV. For this problem, assume that Tc-99m is present in the...
