For the some unknown Hamiltonian, we will use a trial wave function ?? = ??₁??₁ + ??₂??₂ . Where ??1 ?????? ??2 are known functions

a. What are the variational parameters of this trial wave function (2 points)?

b. Minimizing the average energy will lead to a secular Determinant.Write down an expression for the Secular Determinant for this system using the following symbols (4 points)

??_11, ??₁₂ = ??_21, ??₂₂, ??_11, ??₁₂ = ??_21, ??_22, E.

c. Write a mathematical expression using ??₁, ??₂, and any necessary operators to define (2 points)

??₂₂=

??₂₁=

1).a) Show that the bound state wave function ψb (Eqn 2.129) and the continuum state wave function ψk (Eqn 2.131-132 with coefficients 2.136-137) are orthogonal, i.e., 〈ψb|ψk〉 = 0. (b) [bonus] Explain why the orthogonality exists, example as, are they eigenstates of an operator? If so, what is the operator? If not explain.

Use the Schrodinger equation solution of the H atom corresponding to its wave function for the 3dxy orbital to explain why this orbital has no radial node. Questions to consider: (j) What is the value of the wave function and thus the radial part of the function at a node? (ii) What factor of the radial part of the wave function, containing r, can equal your value in (i) and thus allow you to obtain a value for r?
