Using two different methods of calculation of the imaginary part of some Feynman integral, the author obtains an explicit formula for a definite integral (over z from 0 to a) with modified Bessel function I0(z) and weight function w(z)=z cosh (AZ) mod Z, where Z= square root (a2-z2), and A and a are real parameters.
