(A) At what frequency will we observe spectroscopic transitions between the nuclear spin states of a bare proton when the imposed magnetic field is 2.3486 T? To what wavelength does this frequency correspond? (B) If we fix the frequency at 1.75 x 10% s, what magnetic field will be required to satisfy the resonance condition for spectroscopic transitions between nuclear spin states of a proton, Use y= 26.752 x 10/Ts.

According to the article Alien Antimatter Crashes into Earth 2 : More than 60 years ago, future Nobel laureate Sheldon Glashow predicted that if an collided with an antineutrino the antimatter answer to the nearly massless neutrino electron, it could produce a cascade of other particles. The "Glashow resonance - phenomenon is hard to detect, in large part because the antineutrino needs about 1,000 %3D times more energy than what's produced in the most powerful colliders on Earth. Let's compare this event to an ordinary baseball with a mass of 146 g. Please use three significant figures in your calculations.

Question:  The radionuclide Tc-99m is a gamma photon emitter. The emitted gamma photonenergy is 141 keV. The scintillation crystal in a Gamma camera will convert the single gammaphoton to a burst of visible photons. Assuming the generated visible photons wavelength is 550nm, calculate how many visible 550-nm photons will have the same amount of energy as a single141-keV gamma photon?

A certain medium has the following properties: Σs = 0.1 cm−1,Σa = 0.01 cm−1. a) What is the probability that a neutron will travel 1 cm in this medium without interacting with a nucleus? b) If the neutron speed is 2 ×105 cm s−1, what is the average time between scattering collisions?
