I think its a suitable sentence. Its a truly abhorrent crime and I'm glad for once its been taken seriously as the effects are potentially as damaging as rape itself (though I'd be interested to know whether there's any evidence for that, as being falsely accused of rape and actually being raped are 2 completely different things), but I don't agree with the comments saying it should get the same as rape itself, surely our justice system doesn't work that way, like said, its slander and/or perverting the course of justice, its a completely different crime.
