Say you want to calculate the mass ratio of sulfuric acid, H2SO4. 1. Determine the Molar Mass of Each Element Present H2SO4contains hydrogen (H), sulfur (S) and oxygen (S). From the periodic table, you can see that the molar masses of these elements are: ...
It is shown that by applying PCAC, the 2β-decay process can be directly related to double-charge-exchange reaction. Therefore, by studying double-charge-exchange reactions one is able to determine the nuclear matrix element of the relevant 2β-decay experimentally. A preliminary analysis has in...
