In principle there's no reason why you can't publish something as an independent researcher in a normal scientific journal. However of course you have to convince them that it's worth publishing and may have to pay publication fees. Other than that try preprint servers like arxiv. Unless your research is obviously bogus they'll usually accept almost anything. If your research is worthy you may still be able to publish it in a peer reviewed journal afterwards.
