What is the explanation for the intensity of the X rays from the nuclear transition following EC in 55Fe compared to x rays from its atomic shell?

According to literature 55Fe decays via electron capture to the 7/2- level of 55Mn (100%). The subsequent gamma decay at 126 keV has an intensity of only 1.3×10-7. However, the vacancy in the...
