Entire functions with preassigned zero proximate order

It is known that if the proximate order $ρ(r)$ such that $\lim ρ(r) = ρ> 0 (r \to \infty)$, then there exists an entire function $f(z)$ of proximate order $ρ(r)$. In the case where $ρ= 0$ the question about the existence of such entire function remained open until now. This question is investigated in the paper.
