Equation [8] has been incorrectly typeset in the final version. The first term in the square parentheses is supposed to be a cube root and not a 3 followed by a square root symbol.

An alternate but correct form of Eq. [8] is:

$$ G_{hkl}^{n} /V_{hkl} \ge a\left[ {\left( {\frac{ - 4\pi }{3ln(1 - \varphi )}} \right)^{\frac{1}{3}} \sqrt {\frac{{N_{0} }}{n + 1}} \left(1 - \frac{{\varDelta T_{n}^{n + 1} }}{{\varDelta T_{tip}^{n + 1} }}\right)} \right]^{n} $$
