Can I use a quantaray lens on a nikon camera?

I have a 55mm quantaray lens on my pentax zx-60 film camera and I'm looking into getting a nikon digital camera, like maybe a nikon d3000. But I'm wondering if I can just put my 55mm on it and getting just the body rather than the lens and body.

Not directly, and adapting the lens isn't a good option. Get a kit lens with your D3000 and it will be much better.

Maybe if you could replace the mount to a Nikon-F. I wouldn't personally bother doing it as it may cost more than the lens itself.
