Splet12. sep. 2024 · The radius of a nucleus is given by Equation 10.2.1. Substituting the values for r0 and A yields r = (1.2fm)(56)1 / 3 = (1.2fm)(3.83) = 4.6fm. Density is defined to be ρ = m / V, which for a sphere of radius r is ρ = m V = m (4 / 3)πr3. Substituting known values gives ρ = 56u (1.33)(3.14)(4.6fm)3 = 0.138u / fm3.
