Let \overline{a}, \overline{b}, and \overline{c} be three unit vectors such that \overline{a} \times(\overline{b} \times \overline{c})=\frac{1}\sqrt{2}(\overline{b}+\overline{c}) and \overline{b} is not parallel to \overline{c}. If \alpha and \beta are the angles between \overline{a}, \overline{b} and \overline{a}, \overline{c} respectively then \alpha-\beta=
