Qualitatively, how would you expect the probability for a particle to tunnel through a potential barrier to depend on the height of the barrier? Explain.
In what ways do atoms in a diatomic molecule behave as though they were held together by a spring? In what ways is this a poor description of the interaction between the atoms?
Under what conditions is average velocity equal to instantaneous velocity?
Compare the wave functions for the first three energy levels for a particle in a box of width L(see Fig. 40.12a) to the corresponding wave functions for a finite potential well of the same width (see Fig. 40.15a). How does the wavelength in the interval 0≤ x ≤ L for the n= 1 level of the particle in a box compare to the corresponding wavelength for the n= 1 level of the finite potential well? Use this to explain why is less than in the situation depicted in Fig. 40.15b.
Since lead is a stable element, why doesn’t the decay series shown in Fig. 43.7 stop at lead, ?
