[en] A supersymmetric quantum algebra is generated by irreducible tensor operators in respect to the algebra su_q(2). The even generators are realized as tensor products of q-boson creation and annihilation operators, transforming as su_q(2) spinors and acting as odd generators. In this way the transformation properties of all the algebra's generators in respect to the q-deformed algebra of the angular momentum are simultaneously preserved, which is important in view of future applications in physics. In the limit q → 1 the classical Lie superalgebra sp(4,R) or the osp(1|4) is recovered. (author). 27 refs
