According to Wikipedia:


 * "The original spelling of the character's name was "Elizabeth", though relettering of the UK versions for American reprints would occasionally misspell it as "Elisabeth". This led to spelling inconsistencies throughout future publications. The inconsistency was resolved by Claremont 32 years later in 2008 in the series New Exiles, which reasserted the particular spelling of her name as "Elizabeth"."

So it seems that in the US it is Elizabeth while Elisabeth was an error present for only one country.

Also, according to Marvel's official website (http://marvel.com/universe/Psylocke#axzz4zE3pZnuL) it's Elizabeth.
