Abstract: We consider a certain family of infinite products, denoted $ f_{a,b}$, which were introduced by Han as a generalization of the Nekrasov-Okounkov formula. Extending the work of Serre on powers of Dedekind's $ \eta$-function, we investigate the integers $ a$ and $ b$ for which ``almost all'' of the Fourier coefficients of $ f_{a,b}$ are zero (forms with this property are referred to as lacunary). We give the complete list of pairs $ (a,b)$, where $ b$ is odd, for which $ f_{a,b}$ is lacunary.
