2. A particle of mass m in the infinite square well of width a at time 1 - 0 has wave function that is an equal weight mixture of the two lowest n= 1,2 energy stationary states: (x,0) - C[4,(x)+42(x)] (a) Normalize the wave function. Hints: 1. Exploit the orthonormality of W, 2. Recall that if a wave function is normalized at t = 0, it stays normalized. (b) Find '(x, t) and (x,1)1at a later time 1>0. Express Y*...
18. A given particle-wave has a (normalized) Gaussian probability density Le-**/(2a), where a = 1 Å. What are the standard devi- ations of the position and momentum of this particle?
Consider a particle confined to one dimension and positive with the wave function Nxear, x20 x<0 0 where N is a real normalization constant and α is a real positive constant with units of (length)-1. For the following, express your answers in terms of α: a) Find the normalization constant N. What are the units of your result and do they make sense? b) What is the most probable location to find the particle, or more precisely, at what z...
#4-42 Quantum Chemistry- McQuarrie 2nd edition uion or the for a particle in a box in a state described in the previous problem. Plot your result through one cycle. blem, we shall develop the consequence of measuring the position of a particle 4-42. In this box. If we find that the particle is located between a/2-/2 and a/2+/2, then its wave function may be ideally represented by a/2 - /2 <x <a/2+/2 x > a/2+/2 Plot ?(x) and show that...
The initial wave function of a free particle is: Ψ(x,0) = A, for |x| = 0, otherwise where a and A are positive real numbers. The particle is in a zero (or constant) potential environment since it is a free particle a) Determine A from normalization. b) Determine φ(p) = Φ(p,0), the time-zero momentum representation of the particle state. What is Φ(p,t)? Sketch φ(p). Locate the global maximum and the zeros of φ(p). Give the expression for the zeros (i.e.,...
