Finite languages $L\in RE$
The answer is no. Every finite language is regular, and thus decidable. Therefore the existence of a finite language $L$ in $ \text{RE} \setminus \text{R}$ is impossible. However, note that there languages $L$ in $\text{RE}\setminus \text{R}$ (e.g., $Halt_{TM}$), and by what we have seen previously, such languages have to be infinite.
