Topic 8 - Nuclear Physics

Question 1

If we are trying to estimate the nuclear radius by finding the nuclear diameter, what equation do we need to use?

Answer 1

R x sin(theta-min) = 0.61 x lambda.

R = radius of nucleus.
sin(theta-min) = sine function of minimum angle.
Lambda = de broglie wavelength of electrons.

Question 2

In the nuclear radius equation, what does Ro mean?

Answer 2

It is a constant - Ro = 1.05 fm where 1 fm = 10^-15m.
