太阳中微子谱中的极能谱线

The Extreme Energies Lines in the Solar Neutrino Spectrum

B. I. Goryachev

摘要:

本文考虑了太阳氢循环中的氚链,包括反应^3He(e^-,ν_(e))^(3)H(p,γ)^(4)He。在1 a.u.的距离处,氚中微子的通量等于8.1 \cdot 10^(4)cm^(-2)s^(-1)。它比(hep)中微子的通量高一个数量级。计算了太阳内部^(3)H中微子产额的径向分布及其在(2,5 ~ 3,0)keV处的线形能谱。热氚中微子流伴随着能量低于18,6 keV的非常弱的反中微子流(~ 10^(3)cm^(-2)year^(-1))。这些反中微子是在厄卡号^3He<=>^3H的过程中产生的。估算了由(hep)反应(与(hep)过程有关)产生的最大可能能量(19.8MeV线)中微子的通量

英文摘要:

Tritium chain of the hydrogen cycle in the Sun including reactions ^3He(e^-,ν_(e))^(3)H(p,γ)^(4)He is considered. At the distance of 1 a.u. the flux of tritium neutrinos is equal to 8.1\cdot 10^(4) cm^(-2)s^(-1). It is an order of magnitude higher than the flux of the (hep)-neutrinos. Radial distribution of ^(3)H-neutrinos yield inside the Sun and their energy spectrum which has a form of line at the energy of (2,5 ÷ 3,0) keV are calculated. The flux of thermal tritium neutrinos is accompanied by a very weak flux of antineutrinos (~ 10^(3) cm^(-2)year^(-1)) with energy lower than 18,6 keV. These antineutrinos are produced during Urca processes ^3He<=>^3H. The flux of the neutrinos of maximum possible energy (line 19,8 MeV) produced due to the (heep)-reaction (related to the (hep)-process) is estimated
