Nazin S. Cryogenic electrolytes [Електронний ресурс] / S. Nazin, I. Chikina, V. Shikin // Физика низких температур. - 2013. - Т. 39, № 5. - С. 611-616. - Режим доступу: http://nbuv.gov.ua/UJRN/PhNT_2013_39_5_19 The emphasis is made on experimentally observed indications of the presence of metastable ion dipoles in solid helium. Similar quasiparticles possessing positive scattering length for injected electrons are assumed to exist in liquid phases of cryogenic liquids. The observed phenomena allowing to detect and monitor the behavior of dipole gas in superfluid helium (referred to as cryogenic electrolyte) are discussed. Most interesting among these phenomena are: special features of the dielectric behavior of ion dipole gas, details of the temperature dependence of the ion dipole gas osmotic pressure at the boundary of the liquid <^>3He - <^>4He solution stratification, relaxation phenomena of collective origin in cryogenic electrolytes, and liquid helium phonon spectrum transformation due to strong interaction between phonons and heavy dipole quasiparticles.

Shikin V. Relaxation phenomena in cryogenic electrolytes [Електронний ресурс] / V. Shikin, I. Chikina, S. Nazin // Физика низких температур. - 2013. - Т. 39, № 6. - С. 712-715. - Режим доступу: http://nbuv.gov.ua/UJRN/PhNT_2013_39_6_13 Proposed is a scenario for development of observed relaxation phenomena in the cryogenic electrolyte with the structure of "liquid hydrogen + injected ions". Ions of one sign are generated in the bulk of liquid hydrogen in the presence of external field <$EE sub symbol <94>> by a stationary radioactive source of <$Esymbol С~roman ions> at the bottom of the vessel. After accumulation near the free surface of the liquid with a finite density <$En sub s> the ions can break its stability producing a pulse of ion current to the collector located above the liquid surface. The outlined process is periodically repeated. Its period contains information on the ion mobility and, which is most interesting, on dissociation (association) processes occurring in a system of charged particles placed in an external field. The cryogenic problem is a good model for dissociation in the presence of external field occurring in normal electrolytes without any external ion sources.

Chikina I. Dynamic phenomena for charged clusters in cryogenic liquids [Електронний ресурс] / I. Chikina, S. Nazin, V. Shikin // Физика низких температур. - 2011. - Т. 37, № 5. - С. 500-504. - Режим доступу: http://nbuv.gov.ua/UJRN/PhNT_2011_37_5_9 Discussed in the paper are resonance phenomena in electrolytes related to possible relative motion of the charged core and hydrate (solvate) shell of each cluster. The resonances are shown to contain important information on the internal structure of clusters. Special attention is paid to the process of formation of the cluster associated mass in the solvent.

Shikin // Физика низких температур. - 2011. - Т. 37, № 5. - С. 505-508. - Режим доступу: http://nbuv.gov.ua/UJRN/PhNT_2011_37_5_10 Discussed in the paper are possibilities for description of electron conduction in transitional density range separating electron free and localized states in cryogenic media.
