87SR c |b spectral shape was measured with the following techniques: 4|p
87SR2c proportional counter (1973Ru02), NaI(Tl) scintillator
87SR3c (1961Be41,1961Eg01), doped liquid scintillator (1959Fl40).
87SR c The measured spectrum shape is in agreement with the assumed
87SR2c non-unique third-forbidden decay.
87SR c Earlier |b spectral shape factors were analyzed in terms of nuclear
87SR2c matrix elements by 1969Sa02, 1971Ko28, and 1976Sz03.
