    "abstract": "The hamiltonian describing a single fermion in a Penning trap is shown to be\nsupersymmetric in certain cases. The supersymmetries of interest occur when the\nratio of the cyclotron frequency to the axial frequency is 3/2 and the particle\nhas anomalous magnetic moment 4/3 or 2/3. At these supersymmetric points, the\nspectrum shows uniformly spaced crossed levels. The associated superalgebras\nare su(2|1) and su(1|1). The phase space for this problem has an osp(2|6)\nstructure and contains all the degeneracy superalgebras.",
