Abstract
The equations which are currently used to calculate intervalley mixing for shallow impurity states in semiconductors are examined critically. It is shown that terms which have been neglected so far can be responsible for effects of the same order of magnitude as the ones considered. Evidence is given for this by means of qualitative and numerical arguments in the case of donor impurities in silicon.Keywords
