Interpretation Introduction

(a)

Interpretation:

The nuclear symbol for a beta particle is to be stated.

Concept introduction:

When a narrow beam is aimed into an electric field, it divides into three beams. These three beams indicate that radioactive emissions are made up of three different products. These three products are alpha particles, beta particles, and gamma particles. Alpha, beta, and gamma are the radioactive particles.

Interpretation Introduction

(b)

Interpretation:

The name for the Greek letter γ is to be stated.

Interpretation Introduction

(c)

Interpretation:

The most penetrating and the least penetrating among the radiations alpha, beta, and gamma are to be stated.

Consider the nuclide cobalt-59 (5927Co). (a) The mass of 5927Co in atomic mass units is 58.933200 u. (Note this is the mass of the entire atom, not just the nucleus.) This mass is lower than the total mass of its constituent protons, neutrons, and electrons. Find the difference, in atomic mass units, between the total mass of the constituent particles, and the actual mass of the nuclide. (This is sometimes called the "mass defect.") The mass of a proton is 1.007276 u, the mass of a neutron is 1.008665 u, and the mass of an electron is 5.486 ✕ 10−4 u. (Round your answer to at least four decimal places.)   b) Since, according to special relativity theory, mass and energy are "equivalent," the mass defect, or "missing" mass found in part (a), is measurement of the energy it would take to break the bound 5927Co atom into its constituent particles. In other words, it is equivalent to the binding energy. Using the result of part (a), find the binding energy per nucleon, Eb/A for 5927Co in…
