3. A beam of helium-3 atoms (m = 3.016 u) is incident on a target of nitrogen-14 atoms (m = 14.003 u) at rest. Dur- ing the collision, a proton from the helium-3 nucleus passes to the nitrogen nucleus, so that following the col- lision there are two atoms: an atom of "heavy hydro- gen" (deuterium, m = 2.014 u) and an atom of oxygen-15 15.003 u). The incident helium atoms are moving at (m a velocity of 6.346 × 10° m/s. After the collision, the deu- terium atoms are observed to be moving forward (in the same direction as the initial helium atoms) with a velocity of 1.531 x 10' m/s. (a) What is the final velocity of the oxygen-15 atoms? (b) Compare the total kinetic energies before and after the collision.

A beam of alpha particles is incident on a target of lead. A particular alpha particle comes in “head-on” to a particular lead nucleu and stops 6.50 * 10-14 m away from the center of the nucleus.

6. One form of nuclcar radiation, beta decay, occurs when a neutron changes into a proton, an clectron, and a neutral particle called an antineutrino: n → p+ + e¯ +Ve, where ve is the symbol for an antincutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the clectron and neutrino are ejected from the nucleus. The ejected electron is called a beta particle. One nucleus that exhibits beta decay is the isotope of hydrogen ³H, called tritium, whose nucleus consists of one proton (making it hydrogen) and two neutrons (giving tritium an atomic mass m = 3u). Tritium is radioactive, and it decays to helium: 3H → *He + e¯+Ve• (a) Is charge conserved in the beta decay process? Explain. (b) Why is the final product a helium atom? Explain. (c) The nuclei of both 3H and 3He have radii of 1.5 x 10 15 speed must the electron be ejected if it is to escape from the nucleus and not fall back? m. With what minimum
