On the Fermi Surface Shapes of the Noble Metals by Ultrasonic

Some revised conclusions are given concerning the Fermi surface shades of the noble metals as determined ultrasonically. The main new conclusions are: (a) The relative amount of zone boundary touching in copper and gold is nearly the same. (b) There is evidence that the main bodies of the surfaces are considerably more distorted than previously believed, being bulged outward along [100] and possibly being concave in the [110] direction.
