Detailed I.R. Study of the Phase Transition in the System AgNO3-Fe(NO3)3

A complete infrared study of the mixed crystal system of AgNO₃ and Fe(NO₃)₃ is carried out in the region 400–4000 cm^?1. The study includes internal fundamental normal vibrations of the NO₃^? ion in the ordered and disordered phases of AgNO₃ at different values of the ferric concentration, I.R. spectra, spectral band shape intensities, and frequencies of the internal modes as functions of the ferric ion concentration. Special attention is paid to bending mode, combination mode, asymmetric stretching mode, and over-tone. The rotational energy barrier is determined at different concentration of the ferric ions in the system of AgNO₃-Fe(NO₃)₃.

The structure of the “condensed” phase of a finite nucleus is investigated by a HF calculation with a HO-type potential, one-pion-exchange potential and one-rho-meson-exchange potential. The pion field expectation value is also calculated from this nuclear source wave function and compared with the pion field of the normal phase. The time-dependent Schroedinger equation is solved for a certain approximated model of a heavy-ion reaction to see the dynamical growth of the pion field expectation value and its behaviour on such a time scale. The growth of the pion field itself is also investigated to see whether it is a normal growth or that of the condensed phase.
