It's only been a week.... older cats can be very slow to warm up to newcomers. Keep separating them and slowly introducing them to each other.

You can also try feliway. They are cat phermones you plug in like  aglade plug in and can relax and calm your cats. May make them more accepting of pittle kitten. We used them to reintroduce two of our cats who suddenly starte dhating each other after an incident with a plastic bag. It took our cats over two months to stop hissing at each other and to quit spraying in defense. 

Keep at it!
