Abstract

The photoexcitation of a dipole-forbidden resonance in helium was presented. The photoexcitation was observed by measuring the nondipolar forward-backward asymmetry of photoelectron angular distributions in the 2l2l′ autoionizing region. Results showed that the quadrupole resonance in photoabsorption and extracted its Fano line shape parameters and relative phase of the 1sEp and 1sEd continua.
