Question

1. A beam of protons of energy 3.75 MeV is incident on a barrier
of height 18.00 MeV and

thickness 1.65 fm (1.65 x 10^ -15 m). (a) What is the probability
of the protons tunneling through the barrier?

(b) By what factor does the probability change if the barrier
thickness is doubled ?

Answer #1

A beam of protons, each with energy E=20 MeV, is incident on a
potential step 40 MeV high. Graph using a computer the relative
probability of finding protons at values of x > 0 from x = 0 to
x = 5 fm.

Suppose a beam of 4.00 eV protons strikes a potential energy
barrier of height 6.20 eV and thickness 0.560 nm, at a rate
equivalent to a current of 1150 A. (a) How many years would you
have to wait (on average) for one proton to be transmitted through
the barrier? (b) How long would you have to wait if the beam
consisted of electrons rather than protons?

equivalent to a current of 980 A. (a) How many
years would you have to wait (on average) for one proton to be
transmitted through the barrier? (b) How long
would you have to wait if the beam consisted of electrons rather
than protons?

equivalent to a current of 1190 A. (a) How many
years would you have to wait (on average) for one proton to be
transmitted through the barrier? (b) How long
would you have to wait if the beam consisted of electrons rather
than protons?

transmitted through the barrier? (b) How long
would you have to wait if the beam consisted of electrons rather
than protons?

A proton and a deuteron (which has the same charge as the
proton but 2.0 times the mass) are incident on a barrier of
thickness 10.5 fm and “height” 11.1 MeV. Each particle has a
kinetic energy of 2.80 MeV.
a.) Which particle has the higher probability of tunneling
through the barrier?
a. Photon
b. none of them will pass through the
barrier
c. both have same probability
b. What is the ratio of the tunneling probability...

A beam of 1,000,000 electrons, each with kinetic energy E = 1.0
eV, is incident on a potential barrier with the height V0 = 7.0 eV.
(a) How many electrons in the beam will be transmitted through the
barrier if the barrier width a = 0.25 nm? (b) Answer the same
question if the width is doubled, that is, a = 0.5 nm. (c) Briefly
explain the effect of the barrier width in quantum tunneling, based
on your results in...

An electron beam with energy 0.1 eV is incident on a potential barrier with energy 10 eV and width 20 ˚A. Choose the variant that you think best describes the probability of finding an electron on the other side of the barrier: a) 0; b) <10%; c) 100% d) 200%.

An
electron with an energy of 5.5 eV approaches a potential barrier of
height 6.1 eV and thickness of 1nm. What is the relative
probability that the electron passes through the barrier? What
barrier height should be used to decrease the relative probability
by a factor of 100?

Consider an incident beam of 10^4, 2.4 MeV photons on a block of
carbon of thickness 3 × 10^23electrons/cm^2(or 5 ×

photon beam and the block of carbon is Compton scattering. What is
one way you could determine this? State a useful coefficient for
this interaction. B. What is the number of Compton
interactions? C. How much energy is diverted from the
incident beam? D. Calculate the energy transferred to the
