Abstract: In a preceding paper of the author, a new type of an $ \ell $-adic regulator $ \mathfrak{R}_\ell (K)$ was introduced for an algebraic number field $ K$ such that the prime $ \ell $ splits completely in $ K$. Nevertheless, the element $ \mathfrak{R}_\ell (K)\in \mathbb{Z}_\ell $ is defined only up to an arbitrary factor in $ (\mathbb{Z}_\ell ^\times )^2$. In the present paper, under the assumption of the validity of the Shanuel conjecture (both Archimedean and $ \ell $-adic), the definition of $ \mathfrak{R}_\ell (K)$ as a certain number in $ \mathbb{Z}_\ell $ is given. For a real quadratic field $ K$, such a defition can be obtained without using any additional conjectures.
