(a) For the 1s wavefunction, calculate the probability for the electron to be
found within the nucleus, considered to be a sphere of radius R. (b) Evaluate
the probability for a nucleus of lead (R = 1.7 fm). (c) Suppose instead that a
muon (m = 207me) were in its 1s state. What is the probability to find it
inside the lead nucleus?

Find the uncertainty in frequency due to lifetime boradening using the Breit-Wigner formula if the lifetime of an excitation in a Cd/Se quantum dot is 25ns and it emits light at a wavelength of 550nm when it decays.
A particle cannot generally be localized to distances much smaller than its de Broglie wavelength. This fact can be taken to mean that a slow neutron appears to be larger to a target particle than does a fast neutron in the sense that the slow neutron has probabilities of being found over a larger volume of space. For a thermal neutron at room temperature of 300 K, find (a) the linear momentum and (b) the de Broglie wavelength. (c) State how this effective size compares with both nuclear and atomic dimensions.

A proton or a neutron can sometimes "violate" conser- vation of energy by emitting and then reabsorbing a pi meson, which has a mass of 185 MeV/c². This is possi- ble as long as the pi meson is reabsorbed within a short enough time At consistent with the uncertainty principle, (a) Consider p → p + л.

(c) Assuming that the pi meson travels at very nearly the speed of light, how far from the proton can it go? (This procedure, as we discuss in Chapter 12, gives us an
