M. Bokor et al., A POSITRON-ANNIHILATION STUDY ON PHASE-TRANSITIONS IN TRANS-STILBENE SINGLE-CRYSTAL, Journal of radioanalytical and nuclear chemistry, 200(3), 1995, pp. 265-275
Positron lifetime spectroscopic and Doppler-broadening measurements ha
ve been carried out on trans-stilbene single crystals. The results (in
cluding the complementary DSC measurement) give new evidence for the e
xistence of phase transitions in trans-stilbene at temperatures betwee
n 20 and 300 K.
