 Hi, I am trying to compute this integral for different a with 0.0001"PrincipalValue"] where 0>]]))/(-0.64+(0.8 -x)^2)^2+E^(-(0.1/Sqrt[1-Power[<<2>>]]))/(-0.64+(0.8 +x)^2)^2 has evaluated to Overflow, Indeterminate, or Infinity for all sampling points in the region with boundaries {{0.,2.7247563*10^-30}}. I still can't control the accuracy of the calculation. I proceeded by increasing WorkingPrecision, PrecisionGoal, MaxRecursion but it gives each time different values, I do not even know if it gives the true value.Please, how to increase the precision of this computation?Problem not solved yet on stackexchange.

 Have you tried other NIntegrate methods?
 Isn't the principal value divergent (to +∞)? There's a pole of order 2 at x == r`.
