Medical Physics often use the isotope 18F, which decays by positron emission. (i) What mechanism competes with positron emission during nuclear decay(it is more important in heavier isotopes than in light isotopes like 18F)? (j) During positron emission, another particle also is ejected from then nucleus. What is this particle?
