p-^(11)B 三体级联衰变连续能谱测量与干净聚变核能源

EXPERIMENTAL SPECTRA OF p 11 B SUBSEQUENTIAL DECAY ASSOCIATED WITH CLEAN FUSION FUEL

借助ＰＩＰＳ新型探测器和ΔＥ穿透型探测器，首次得到１１Ｂ（ｐ，２α）４Ｈｅ级联衰变连续能谱，为准确获得ｐ－１１Ｂ截面测量提供了实验依据。同时利用系统能量分辨率达１３．９ｋｅＶ的带电粒子谱仪对另一影响截面精确度的因素——靶成份进行了实验分析。

Spectra of 11 B(p,2α) 4He subsequential decay via the first excited state of 8Be were measured by using PIPS and ΔE detector system. In the measurement of absolute cross sections the content analysis of boron target was also performed by charged particle spectrometer with 13 9 keV systematic energy resolution.
