... This problem is similar to projectile problems. The proton acceleration produced by electric force acting acting on the positively charged proton plays the same role in this problem as the acceleration due to gravity in projectile problems. The initial velocity of the proton is vi = 9.55 × 103 m/s . ...

... Since single-particle Hamiltonian Ĥ0 continues to commute with the angular momentum operator, [Ĥ0 , L̂] = 0, its eigenfunctions remain indexed by quantum numbers (n, #, m! , ms ). However, since effective potential, V (r ) + Ui (r ), is no longer Coulomb-like, # values for a given n need not be de ...
