Formulas and Key Relations

Composition of Nucleus

A = Number of protons + Number of neutrons

N = A - Z

Charge on up quark = +2/3 e; charge on down quark = -1/3 e

Size, Shape, and Density of Nucleus

R = R0 A^(1/3)

R = 1.2 A^(1/3) F

(4/3) π R^3 ∝ A or R ∝ A^(1/3)

M = mA

ρ = M/V = mA / [(4/3)π R0^3 A] = 3m / (4π R0^3)

Atomic Mass Unit and Masses

1 u = (1/12)(mass of one 6C12 atom) = (1/12)(12/N gram) = 1/N gram

ΔE = (Δm) c^2

1 u × c^2 = 931.5 MeV
