Help needed :
I can't - and Mathematica 5.0 can't either - integrate this :


In[1]:=
Integrate[x^2 / E^(a*(1 - 2*x^2)^2), {x, 0, 1}, Assumptions -> a >= 0]

Out[1]=
(2*Integrate`TableDump`c$70*E^Integrate`TableDump`c$70^2 -
    Sqrt[Pi]*Erfi[Integrate`TableDump`c$70])/E^(5*a)/
  (4*Integrate`TableDump`c$70^3)


Thanks in advance for any hint.

v.a.
