Abstract: | It is shown that exp(−2 Im(∫ p dr)) is not invariant under canonical transformations in general. Specifically for shells tunneling out of black holes, this
quantity is not invariant under canonical transformations. It can be interpreted as the transmission coefficient only in the
cases in which it is invariant under canonical transformations. Although such cases include alpha decay, they do not include
the tunneling of shells from black holes. The simplest extension to this formula which is invariant under canonical transformations
is proposed. However, it is shown that this gives half the correct temperature for black holes.
