I want to know the answer to the following question:
According to Heisenberg and Schrödinger, the reduced Planck constant remains what?
All the background I'm provided with is that "The correct quantization rules for electrons – in which the energy reduces to the Bohr model equation in the case of the hydrogen atom – were given by Heisenberg's matrix mechanics in 1925 and the Schrödinger wave equation in 1926: the reduced Planck constant remains the fundamental quantum of angular momentum.". Is that enough to answer the question?
