摘要:

我们测量了W-180核的热中子俘获截面。此截面上只有一个先前数据,值为30 $^{+300%}_{-100%}$谷仓。为了将w-181视为低能中微子源,需要更精确地测量热中子俘获截面,以估算核反应堆内w-181的产生率。我们用天然钨箔测量了W-180的截面,得到了一个新的值21.9 $\pm$ 2.5 barn

英文摘要:

We have measured the thermal neutron capture cross section for w-180 nucleus. There is only one previous data on this cross section with a value of 30 $^{+300%}_{-100%}$ barn. To consider w-181 as a low energy neutrino source, the thermal neutron capture cross section should be measured more precisely to estimate the production rate of w-181 inside a nuclear reactor. We measured the cross section of w-180 with a natural tungsten foil and obtained a new value of 21.9 $\pm$ 2.5 barn
