__Angular momentum in quantum mechanics__

In quantum mechanics, angular momentum is quantized – that is, it cannot vary continuously, but only in "quantum leaps" between certain allowed values. The orbital angular momentum of a subatomic particle, that is due to its motion through space, is always a whole-number multiple of h(bar).

If I am not wrong, it is the Orbital angular momentum quantum number which takes whole-number values and not the Orbital angular momentum itself. The magnitude of the Orbital angular momentum is in-fact,

[tex]\sqrt{[l(l+1)]}[/tex]h(bar)

Oh God! Sometimes even simple things create confusion...
