A New Radio Transmission Phenomenon

Abstract

EDITOR 705where n and n' denote neutrino and antineutrino, respectively. The processes (a) and (b) were considered by Wolfe and Uhlenbeck 3 on the basis of the original Fermi theory.For processes (a) and (b) we find for the reciprocal of the lifetime (mc7/r)G 2 [i(V+l) 3/2 arcsinh r^rf-HW+l) 1 ' 2 arcsinh 770 + (l/105)V-(l/15)7 ? o 5 -^o 3 -fr ?0 ]. (2) G is the dimensionless constant gm 2 c/(2ir z ) ll2 h*= 10~1 3 and 770 is (A 2 -1) 1/2 where mA is the mass difference of proton and neutron. Transitions (a) and (b) can occur only if A>1, either one occurring depending on the sign of the mass difference. One can obtain this formula by putting |M| 2 = 1 and integrating Eq. (12) of Konopinski's and Uhlenbeck's paper from 1 to Wo.For small values of (A-1) the lifetime is given by r = 10 6 (A-l)-n / 2 .Taking for the masses of the neutron and proton the recent values given by Bethe 4 we find for the lifetime from Eq. (2) T = 3 X10 5 seconds.or about 3J days. This value, unfortunately, is much too large to be verified experimentally at present. The process (c) will occur when the antineutrinos accompanying beta-rays collide with a nucleus. The result of this collision will be the absorption of the antineutrino •with the emission of a positron. The cross section for this process is <r~G>(h/mc)Kwhich is of the order of 10~4 7 cm 2 . This is smaller than the cross section for the creation of pairs by beta-rays by a factor of about 10-)8 . 5

Unique examples of solar flare effects in geomagnetic H field during partial counter electrojet along CPMN longitude sector

“…Later, it was discovered that chromospheric eruptions, geomagnetic crochet and short wave fadeouts (SWF) were concomitant phenomena (Dellinger, 1935;Torroson et al, 1936;Fleming, 1937;Richardson, 1937). McNish (1937) examined the effects of above mentioned three events in 1936 on the magnetic recordings at 18 stations in Western Europe, America and southern Pacific areas.…”

Solar flare effects on the geomagnetic elements during normal and counter electrojet periods

“…Dellinger (1935) reported simultaneous occurrence of short wave fade out (SWF) during the crochet time. The concomitant phenomena of solar flare, crochet and short wave fade out soon received much interest of many scientists (Fleming, 1936;Richardson, 1936;Torreson et al, 1936).…”

Geomagnetic solar flare effects: a review

“…During the 1930s, Dellinger (1935) carefully studied the fading of high-frequency radio waves ("fade-out") over Europe and North America. For the event of May 12, 1935, Topical Issue -Space climate: The past and future of solar activity 11 h 57 m-12 h 00 m, he discovered a correspondence with solar activity.…”
