7. A particle of rest energy 800 MeV decays in its rest frame
into two identical particles of rest energy 250 MeV. What are the
kinetic energies (in MeV), momenta (in MeV/c), and velocities (in
units of c) of the daughter particles?
A particle of rest energy 800 MeV decays in its rest frame into
two identical particles of rest energy 250 MeV. What are the
kinetic energies (in MeV), momenta (in MeV/c), and velocities (in
units of c) of the daughter particles?
Refer to the previous problem. The parent particle moves in the
lab with kinetic energy 800 MeV, and one daughter particle is
emitted along the parent’s direction of motion. Find the lab
kinetic energy (in MeV) for the daughter...
A particle with rest energy 8.940 GeV decays at rest into two
daughter particles, one with rest energy 6.720 GeV and the other
with rest energy 130.000 MeV.
(a) What is the mass of the parent particle?
(b) How much energy is released in the decay?
The nuclide 236U decays with emission of an alpha particle with
measured energy of 4.448 MeV and an accompanying gamma photon with
measured energy of 49 keV. What is the product nucleus and does
this particular decay of 236U occur to the ground state or and
excited state of the product nuclide?
A Lithium-5 atom at rest decays into a proton and an \alpha
particle with the release of 3.15×10-13 J of kinetic energies total
of the proton and the \alpha particle. Determine the velocities of
the proton and the alpha particle after the decay. You can assume
the masses are m \alpha = 4mp = 6.64×10-27
kg.
4. Each π+ particle in a beam has a momentum of 800 MeV/c. How
far will the beam travel before approximately 10% of the π+ are
left? The π+ rest energy and half-life (at rest) are 140 MeV and 18
nsec, respectively.
An alpha particle with kinetic energy 13.0 MeV makes a collision
with lead nucleus, but it is not "aimed" at the center of the lead
nucleus, and has an initial nonzero angular momentum (with respect
to the stationary lead nucleus) of magnitude L=p0b, where p0 is the
magnitude of the initial momentum of the alpha particle and
b=1.20×10?12 m . (Assume that the lead nucleus remains stationary
and that it may be treated as a point charge. The atomic number...

1. (a) A 210-MeV photon collides with an electron at rest. What
is the maximum energy loss of the photon?
(b) Repeat (a), but with a proton target rather than an
electron. Is the difference between the results reasonable? Why?
