Use the following information to answer the next question. Magnesium-27 is an isotope of magnesium that undergoes beta negative decay. The half-life of magnesium-27 is 9.45 min. The daughter nucleus of this decay is initially produced in a metastable, excited state. Three gamma photons may be emitted as the mucleus makes transitions from this excited state to the ground state. These transitions are shown in the diagram below. Metastable state 0.1707 MeV Intermediate state 0.8438 MeV Ground state 10. The...

(Figure 1) shows the decay scheme for 137Cs, which has two possible beta decay modes. The first, labeled β1, is a decay directly to the ground state of 137Ba. The second beta decay (β2) is to an excited state 137Ba∗. This excited state subsequently undergoes gamma decay to the ground state. In beta decay, the maximum possible energy of the emitted beta particle is equal to the difference in energy between the initial and final states of the nucleus. The...

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)

Phosphorus-32 (P-32) is used in nuclear medicine as therapeutic
agent in the treatment of several diseases. P-32 has a half life of
14.3 days and decays directly to its ground state by emitting a
beta-minus particle. The decay table for P-32 is given. There are
no excited energy states or other radiation emitted during this
decay; therefore, P-32 is referred to as a "pure beta emitter.
A P-32 sample is prepared in the manufacturing site with
