31. There are two ways PFTs are then detected; using an electron capture detector or negative ion mass spectrometry. 32. The parent isotope of indium-111 is tin-111, with a decay mode of electron capture . 33. In this case can we suppose that a quark up is changed in quark down by this electron capture ? 34. The most common decay mode of a radioisotope of zinc with a mass number lower than 66 is electron capture . 35. It decays by electron capture , then emits de-excitation gamma rays that are detected by a gamma camera. 36. In the most common mechanism, Penning electrons undergo electron capture with atmospheric oxygen to produce O 2 ". 37. However, 154 Dy decays primarily by alpha decay, and 152 Dy and 159 Dy decay primarily by electron capture . 38. However, protons are known to transform into neutrons through the process of electron capture ( also called inverse beta decay ). 39. The nucleus may capture an orbiting electron, causing a proton to convert into a neutron in a process called electron capture . 40. The primary decay mode before the stable isotope, 141 Pr, is electron capture and the mode after is beta decay.
