The cross-section and angular distribution of the D-D reactions below 50 keV

Abstract

A thin gas target was used and the particles from the reactions were detected by a proportional counter. The results show that the total cross-section for the two reactions is the same to within 1%, but that the angular distributions of the products are significantly different. The asymmetry coefficient for the reaction D( d , n ) 3 He is given by 0·31 + 0·0058 E , compared with 0·13 + 0·0047 E for reaction D( d , p ) 3 H, where E is the bombarding energy in kilovolts.

“…Fig. 6 displays the data available for a,(90~ ~ taken from Theus et aL [34], Eliot et al [35], and the values of Arnold et aL [23], corrected by McNeill [41]. The data of Booth et aL [24] and McNeill and Keyser [25] were omitted because of their large error bars.…”

“…For these data points averaged energies have been calculated. The data points of Eliot et al [35], Manning et al [37] and Timm et al [38] have been omitted, either because of their large error bars or because they are too far away from the general trend of the other data points.…”
