Excited Leptons
preliminary: Contributed to EPS97 (Jerusalem) Ref. 615

• N events expected and Form Factor vs Mass
• upper limit on lambda/mass vs mass for charged leptons
• upper limit on lambda/mass vs mass for neutrinos

Unstable Heavy Leptons
preliminary: Contributed to EPS97 (Jerusalem) Ref. 616

• upper limit on the cross section vs mass for heavy Dirac neutrinos
• upper limit on the cross section vs mass for heavy Majorana neutrinos
• upper limit on the cross section vs mass for heavy charged leptons
• excluded region in the (MN,ML) plane for decays into heavy neutral leptons
