%X We  analyze  the  method  of  fundamental  solutions  (MFS)  in  two  different  versions  with  focus  on  the  computation  of  approximate  acoustic  interior  transmission  eigenvalues  in  2D  for  homogeneous  media.  Our  approach  is  mesh-  and  integration  free,  but  suffers  in  general  from  the  ill-conditioning  effects  of  the  discretized  eigenoperator,  which  we  could  then  successfully  balance  using  an  approved  stabilization  scheme.  Our  numerical  examples  cover many of the common scattering objects and prove to be very competitive in accuracy with the standard methods for PDE-related eigenvalue problems. We  finally  give  an  approximation  analysis  for  our  framework  and  provide  error  estimates,  which  bound  interior  transmission  eigenvalue  deviations  in  terms of some generalized MFS output.
