In this work, we prove that the closure of a symmetric operator L0 which is formed by differential expression (L0y)(x) = −(p(x)y (x)) − Q(x)y(x) and with the boundary condition cos α.y(0) + sinα.y (0) = 0 is self adjoint where α ∈ (−∞,∞) in the space L2(0,∞; H ). Furthermore, we investigate some properties of this operator. Mathematics Subject Classification: 47A10, 34L20 Keywords: Closure, Hilbert Space, Self-Adjoint Operator, Symmetric Operator
