Three Dimensional Potential Well: a Three-Dimensional Potential Well Has Potential

question 38

Multiple Choice

Three dimensional potential well: A three-dimensional potential well has potential U₀ = 0 in the region 0 < x < L, 0 < y < L, and 0 < z < 2L and infinite potential otherwise.

• A) 2E₀, single degeneracy
• B) (4/3)E₀, single degeneracy
• C) 2E₀, double degeneracy
• D) (7/3)E₀, double degeneracy
• E) 3E₀, triple degeneracy
