Momentum for a particle in an infinite square well is quantized, existing only in discrete allowed values corresponding to the boundary conditions of the potential well.

The analysis

The retrieved papers address the momentum states, operators, and wavefunctions for a particle in an infinite square well (potential box), confirming standard quantum mechanical principles where spatial confinement leads to discrete (quantized) momentum eigenvalues.
