In this paper, we report the results obtained in the PHoton ELectron EXperiment (PHELEX) during 208 days of measurements in the search for dark photons using a multi-cathode counter with an iron cathode. We observed a systematic excess of single-elec

It was found that at cryogenic temperatures the spontaneous emission of single electrons from cathode of PMT is increased by lowering the temperature of PMT. This effect has not found yet a satisfactory explanation. It was suggested by us that the so

New upper limit on a mixing parameter for hidden photons with a mass from 5 eV till 10 keV has been obtained from the results of measurements during 78 days in two configurations R1 and R2 of a multicathode counter. For a region of a maximal sensitiv

It is shown that it is possible to introduce a mixing in the solar model not in a contradiction with the present data of helioseismology. Particularly it is demonstrated that resulted violation in the sound speed profile is within the uncertainties o

The results of the calculation are presented for the fluxes of CN neutrinos from the Sun in case of mixing in a spherical layer in the solar core, consistent with the seismic data and with the measured solar neutrino fluxes. It is shown that a substa

A lithium-based radiochemical detector is aimed primarily to detect neutrinos from CNO cycle what will provide a direct proof of its existence and will be a stringent test of the theory of stellar evolution. Another task which can be solved by this e

In a future study of solar neutrinos a special emphasis should be given to the measurement of the fluxes of neutrinos generated in CNO cycle, because this is a direct way to measure with record uncertainty - less than 1% the contribution to the solar

We show that a lithium experiment has a potential to confirm or reject the value 1.5% of the solar luminosity attributed to a CNO-cycle by the SSM and to prove that the difference between total energy release of the Sun and what is produced in a hydr
