Fig. 3-1. Schematic view of the detection system for studying the 8 Li(d, t) 7 Li reaction. The
recoiled tritons were measured by using the ∆E-E telescope (43-µm-thick double-sided Si detector
and 375-µm-thick Si detector with a size of 50 x 50 mm 2 ), SSD1 and SSD2 (375-µm-thick Si
detector with a size of 18 x 18 mm 2 ). The scattered 7 Li particles were measured by SSSD1 and
SSSD2 (68-µm-thick single-sided Si detector a size of 50 x 50 mm 2 ) in coincidence with SSD1 and
SSD2. The beam intensity was monitored and its amount was measured by the plastic scintillator
installed just downstream of the Al plate, on which the beam particles were implanted after passing
through the target.
Fig. 3-2. Excitation function of cross section of the 8 Li(d, t) 7 Li reaction. The red circles show the
results of the present study. The open triangles show th results of the previous study [3-1]. Energy
regions of astrophysical interest are indicated by temperatures corresponding to the Gamow peaks
(red arrows).
