At t = 0 it is known that of 1000 neutrons in a one-dimensional box of width 10-5 cm, 100 have energy 4E1, and 900 have energy 225E1.
(a) Construct a state function that has these properties.
(b) Use the state that you constructed to find the density ?(x) of neutrons per unit length.
(c) How many neutrons are in the left half of the box?
