Abstract

The absolute photoionisation cross section of the 11³D Rydberg state of ⁴He has been measured over a range of frequencies very close to the ionisation threshold. The measurements are compared with a calculation of the cross section performed using the quantum defect method, and the agreement is found to be within the +or-20% uncertainty associated with the measurements.
