Abstract
The exactly and quasi-exactly solvable problems for spin one-half in o ne dimension on the basis of a hidden dynamical symmetry algebra of Ha miltonian are discussed. We take the supergroup, OSP(2/1), as such a s ymmetry. A number of exactly solvable examples are considered and thei r spectrum are evaluated explicitly. Also, a class of quasi-exactly so lvable problems on the basis of such a symmetry has been obtained.
