Nuclear magnetic resonance lead-207 parameters

Heat capacity measurements of Holmstrom et al. (1969) (0.02-0.4 K), superseding earher measurements of Anderson et al. (1968), used the same samples as Lounasmaa and, in spite of the impurity problem, by following the procedure outlined in Section 2.4 obtained a value for the magnetic interaction parameter, a in excellent agreement with values obtained by Kalvius et al. (1963) from Mossbauer effect measurements and by Al-Kital et al. (1%7) from neutron resonance measurements. The values are summarized in Part 17.10 and those of Holmstrom et al. (1969) would lead to the following two-term expression for the nuclear heat capacity ...
