Differential cross section of double-stripping nuclear reaction has been calculated with distorted wave Born approximation(DWBA) in ^40Ca(t.p)^42Ca reaction. The angular distribution shape of differential cross section shows large peak in forward. And it has small oscillation. It determines the angular momentum transfer and then the final state of the nucleus is predicted by the angular distribution.
In the ^40Ca(t.p)^42Ca reaction, the angular momentum L of the transfered neutron pair from triton is equal to the total angular momentum of the final state nucleus ^42Ca and the parity of the final state is even.
