%0 Journal Article %T Observations Concerning the Mass Variation in a Galilean - Type Relativity %J - %D 2018 %X By an electric charge model of static type, with spherical distribution of field quanta, periodically emitted, and by the Galilean relativity, there are re-obtained the Lorentz¡¯s expressions of the speed-depending longitudinal and transversal mass of a charged particle accelerated by a quanta flux pressure, as apparent effect generated by a real decreasing of the values of longitudinal and transversal electric field, E L ~ g -3; E T ~ g -1, (¡¤g = 1/£¿(1 ¨Cv 2/c 2), being re-obtained also the general form of the Doppler-Fizeau effect. The invariance of the Lorentz force expression indicates a relativist variation of the magnetic field induction, in the form: B ~g -1, which explains the experimental result of the Kaufmann-Bucherer experiments. It is proposed a classical expression of mass and charge variation, in the form: m = m o/a; q = q o/a, (a = (1 ¨C v 2/2c 2)), which may results as real variation by a significant density of a super-fluid medium of the quantum vacuum containing etherons (m g,s = 10 -60£¿10 -70kg) and quantons (m h = h¡¤1/c 2= 7.37x10 -51kg), by an relativist etherono-quantonic vortex G r (v) which is added to the similar vortex G m (v) of the particle¡¯s magnetic moment which is increased with the speed, if the particle¡¯s spin is rectangular to its impulse. The explicative model may explain also the photon¡¯s energy in correlation with its electromagnetic properties. %K Relativist Mass Variation %K Einstein¡¯s Relativity %K Doppler-Fizeau Effect %K Kaufmann-Bucherer Experiment %K Photon Rest Mass %U http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=124&doi=10.11648/j.ijhep.20180501.15
