1. The problem statement, all variables and given/known data 5) A free particle moving in one dimension is in the state Ψ(x) = ∫ isin(ak)e(−(ak)2/2)e(ikx) dk a) What values of momentum will not be found? b) If the momentum of the particle in this state is measured, in which momentum state is the particle most likely to be found? c) if a=2.1 angstrom and the particle is an electron, what value of energy (in eV) will measurement ﬁnd in the state described in part b? 2. Relevant equations I know tha p=ħk 3. The attempt at a solution I have attempted to complete the integration but this seems to go into very confusing and very difficult terms. I'm thinking that there is something simpler and I am just missing it.
