you have trapped neutrons in a box. What must be the size of the box if you measure photons of the same energy that you emit when the neutrons jump from the n=8 energy state back to ground state. Recall that body temperature is about 37 degrees celcius.
A proton is confined in a uranium nucleus of diameter 7.2 x 10-15 m. Use the energy-level
calculation of a one-dimensional box that has length equal to the nuclear diameter to calculate the
proton's minimum kinetic energy. What is the proton's minimum kinetic energy according to the
uncertainty principle?
A proton is in a box of width L. What must the width of the box be for the ground-level energy to be 5.0 MeV, a typical value for the energy with which the particles in a nucleus are bound? Compare your result to the size of a nucleus—that is, on the order of 10-14 m.

Calculate the de Broglie wavelength for (a) a neutron at room temperature (300 K) and (b) a “cold” neutron at 77 K (liquid nitrogen).arrow_forwardyou have trapped neutrons in a box. What must be the size of the box if you measure photons of the same energy that you emit when the neutrons jump from the n=8 energy state back to ground state. Recall that body temperature is about 37 degrees celcius. (disclaimer: the answer is supposed to be 3.12*10^-10 m but I have not gotten anwsers near that value is it even possible to get the answer mentioned above? Any help in getting and or showing the steps to get the above answer is greatly appreciated!)arrow_forwardPhotons released by nuclear decays tend to be in the MeV range, and atomic nuclei are a few femtometers (10-15 m) across. If a single proton trapped in an inescapable rectangular box releases a 1.3 MeV photon when dropping from the n = 2 to the n = 1 state, how wide is the box, in femtometers? You should find that this quick and dirty estimate is remarkably close to the real size of a nucleus! The proton mass is about 1.7 x 10-27 kg. 1 MeV = 1.6 x 10-13 J. Planck's constant is approximately h = 6.6 x 10-34 J s.arrow_forward
