Abstract
The minimum energy E//p needed to absorb far-infrared radiation in an ensemble of P impurities in Si at T approximately equals 2 K is observed. As the P density n//D is increased, band formation by overlapping 2P//o states of effective radius r//D equals (50 plus or minus 10) A describes E//p, with a zero-crossing at n//D//c equals (2. 9 plus or minus 0. 5) multiplied by 10**1**8 cm** minus **3, near the Mott density.
