5.) Tunneling Effect (14 pts.) In Rutherford scattering, a proton of kinetic energy 10 MeV undergoes a head-on collision with an uranium nucleus. Assume the nucleus to form a square electric potential barrier of height 13 MeV and width 10 fm. (a) Calculate the penetration depth of the proton (in fm). (b) Calculate the transmission coefficient for the proton to reach into the uranium nucleus (possibly inducing fission). 5.) Tunneling Effect In Rutherford scattering, a proton of kinetic energy 10...
Required information A proton in Fermilab's Tevatron is accelerated through a potential difference of 2.70 MeV during each revolution around the ring of radius 1.10 km. In order to reach an energy of 1.10 TeV, how many revolutions must the proton make? revolutions In order to reach an energy of 1.10 TeV, how far has the proton traveled? km
The energy of a proton is 1.0 MeV below the top of a 1.2-MeV-high energy barrier that is 6.8 fm wide. What is the probability that the proton will tunnel through the barrier? (1 eV = 1.60 x 10-19 J, Mproton = 1.67 x 10-27 kg, -h = 1.055 x 10-34 J·s, h = 6.626 x 10-34). s) 1) 11% O2) 9.1% O 3) 14% 4) 7.5%
In addition to its rest energy, a moving proton (p') has kinetic energy. This proton collides with a stationary proton (p), and the reaction forms a stationary neutron (n), a stationary proton (p), and a stationary pion (π+), according to the following reaction: p' + p → n + p + π+. The rest energy of each proton is 938.3 MeV, and the rest energy of the neutron is 939.6 MeV. The rest energy of the pion is 139.6 MeV....
