The partially resolved vibrational fine structure on the C 1s photoelectron line of C{sub 2}H {sub 2} clearly differs from that of other small hydrocarbon molecules such as CH{sub 4} , C{sub 2}H {sub 4} , and C{sub 2}H {sub 6} . This is attributed to photoionization from the two 1{sigma}{sub g} and 1{sigma}{sub u} core orbitals of C{sub 2}H {sub 2} , which can be described as the symmetric and antisymmetric linear combinations of the C 1s orbitals. According to our analysis they are split by 105{plus_minus}10 meV , a result which is in good agreement with calculation. {copyright} {ital 1997} {ital The American Physical Society}
