A particle of positive energy approaches the square well illustrated in fig from the left. some of the wave will be transmitted and some will be reflected.
a) calculate the transmission amplitude
b) show that the transmission amplitude equals 1 when 2k'L = npi, where k'= [sq rt ((2m(E+V_0))/h-bar] is the wavenumber in the region of the well. thus the potential well becomes transparent at a discrete set of energies (Ramsauer effect).
A proton is located at the origin, and a second proton is located on the x-axis at x=6.00 fm. (a) compute the electric potential energy associated with this configuration.
