    "abstract": "We consider the Schwinger\u0027s method of angular momentum addition using the\nSU(2) algebra with both a fermionic and a bosonic oscillator. We show that the\ntotal spin states obtained are: one boson singlet state and an arbitrary number\nof spin-1/2 states, the later ones are energy degenerate. It means that we have\nin this case supersymmetric quantum mechanics and also the addition of angular\nmomentum for massless particles. We review too the cases of two bosonic and\nfermionic oscillators.",
