pd4dThe Pd4d bands extend from 1 to 8 eV in binding energy and the Au 5d bands from 1 to 10 eV below the Fermi level. When the ratio AuPd is 3 to 1 up to 1.5 to 1, the band isResponding to a PD4R notice. You must respond to the PD4R notice and provide an explanation, even if a request has been made to correct the discrepancy.. The response can be sent using:
