Which electeonic transition in Li^(+2) will emit photon of same energy as that emitted due to transition from 5^(th) excited state to 1^(st) excited State in He^(+) .

The photon emitted due to electronic transition of 5^(th) excited state to 2^(nd) excited state in Li^(2+) , is used to excite He^+ already in first excited state. He^+ ion after absorbing the photon reaches in an orbit having total energy equal to :
