by aluminlum shows the presence of a very short range component issuing from the platinum surface. This component makes a noticeable contribution to the count-rate up to an absorber thickness of 80 mg Al/crn s. I t is observed with approximately the same relative intensity if the needle is surrounded by platinum, but it is absent if the needle is surrounded by aluminium. I t is reasonable to as...
