Kv. Aleksandrov et al., Cascade multiplication of a 26-GeV electron shower in a lead plate-emulsion sandwich chamber, TECH PHYS L, 26(6), 2000, pp. 499-501
The electron-photon shower development in a lead plate-emulsion sandwich ch
amber with a total effective lead thickness of 3.5 radiation units was stud
ied for an electron energy of 26 GeV. The experimental electron multiplicat
ion coefficient (P-exp = 19.4 +/- 1.4) agrees with a theoretical value (P-c
alcd = 20.4) calculated with corrections for the particle scattering and ab
sorption. (C) 2000 MAIK "Nauka/Interperiodica".
