The experimental data are evaluated for known nuclides of mass number A=43 (Al,Si,P,S,Cl,Ar,K,Ca,Sc, T i , V , C r ) .

This work supersedes earlier full evaluations of A=43 published by 2001Ca24 and 1990En08 (also 1978En04, and 1998En04 update).No excited states are known in 4 3 Al, 4 3 Si and 4 3 Cr. Only one excited state is known in 4 3 V which is the probable the Isobaric Analog State (IAS) of 4 3 Cr ground state. Information for 4 3 P, 4 3 S, 4 3 Cl, 4 3 Ar and 4 3 Ti is limited; t h e r e i s e i t h e r n o d e c a y d a t a a v a i l a b l e o r t h e d e c a y s c h e m e s a r e i n c o m p l e t e i n v i e w o f l a r g e Q v a l u e s a n d k n o w n e x c i t a t i o n s m u c h l o w e r t h a n a l l o w e d b y Q v a l u e s .
