  It is argued that although quantum theory isn't an absolutely deterministic
theory, it is partially deterministic. The approach followed here is in the
framework of the standard (Copenhagen interpretation of) quantum mechanics
without any additional assumption or alternative interpretation. The argument
is based on the conceptual meaning of determinism and by means of some
well-known phenomena in the quantum world (measurement of a quantum particle
spin, energy values and spatial states of an electron in atoms, the so-called
wavefunction collapse problem) which are usually considered in rejecting
determinism.
