چکیده انگلیسی
The influence of the soliton on the properties of the Mössbauer effect arising from a gamma-active nucleus situated at a lattice site in the organic molecular crystal, which being in contact with a thermostat at Tâ 0, has been theoretically studied. An expression for the gamma-radiated Mössbauer transition probability as a function of temperature has been obtained. The results show that the transition probability is different from that in the case when the molecular crystal state is adequately described exclusively by thermal phonon modes. Finally, we give some properties of the kind of effect by numerical calculation in such a case which are helpful to facilitate further the experimental confirment of the soliton existence in the molecular crystals by using the method of Mössbauer effect.
