text: A deuteron nucleus is made from a proton and a neutron, and so using the aforementioned convention that protons and neutrons have intrinsic parities equal to + 1 {\displaystyle +1} they argued that the parity of the pion is equal to minus the product of the parities of the two neutrons divided by that of the proton and neutron in the deuteron, explicitly ( − 1 ) ( 1 ) 2 ( 1 ) 2 = − 1 {\displaystyle {\frac {(-1)(1)^{2}}{(1)^{2}}}=-1} .
