X-Ray Yields from Elements in the Range Beryllium to Aluminium

Abstract

ABSOLUTE measurements have been made, it is believed for the first time, of the K X-ray quantum yields resulting from electron bombardment of solid targets containing the elements beryllium, boron, oxygen and fluorine. For beryllium and boron 99 per cent pure targets were used while beryllium oxide and lithium fluoride were used for the oxygen and fluorine yields; corrections were applied for electron and X-ray absorption in the beryllium and lithium respectively. The yields from carbon (graphite) and aluminium targets have also been measured.
