Time dependence of the magnetization and ESR in AgMn spin-glass.

Abstract

The purpose of this Comment was to point out and show that a suitably designed electron spectrometer, such as the one used in this test as well as in previous measurements performed in this laboratory, and probably others with well-defined source and image collimation, is able to sort out and even not to transmit electrons that originate from Rydberg atoms ionized in the deflector field. We also observe that the zero signal seen in the corners of the distribution shown in Fig. 2(b) of Ref. 1 and in Figs. 3(a) and 3(c) down to angles as small as 50 mrad disagrees with known evidence according to which the emitted electrons cover an extensive angle-energy area around the cusp.
