 84KR C  1982Gr07: Ge(Li), FWHM=2.0 keV at 1.33 MeV. Measured E|g, I|g.
 84KR C  1979Gr01: Ge(Li). E|g precision measurement making use of
 84KR2C  cascade-crossover relationships.
 84KR C  1970Go44: Ge(Li), CsI, NaI. Measured |b|g, X|g. Deduced |e/|b{++}.
 84KR C  1971Bo01: magnetic spectrometer. Measured |b{++} spectra.
 84KR C  See also 1966He11, 1971Ge10, 1958Ko92, 1967Vr07.
 84KR C  Measurements of special observables:
 84KR C  |b|g directional correlation: 1971Ma43, 1969De21, 1965Si09
 84KR C  |b|g circular-polarization correlation: 1973Sc02, 1963Bo20
 84KR C  |b{++} endpoint energy and spectrum shape factor: 1980HuZS,
 84KR2C  1971Bo01, 1964La03, 1958Be81.
 84KR C  Extraction of matrix elements and theoretical analysis are
 84KR2C  reported by 1980HuZS, 1973Sc02, 1971De02, 1971Ma43, and 1965Si10.
 84KR C  The |g|g(|q) measurement of 1965Ro06 disagrees with other
 84KR2C  experiments (see {+83}Kr(n,|g) and {+84}Br |b{+-} decay (31.76 min))
 84KR3C  and was therefore not adopted by the evaluators.

 84KR2cE and |eL(exp)/|eK(exp)=0.119 {I2} (1970Go44);
 84KR3cE other measurements: |e/|b{++}=5.75 {I7} (1971Ge10); |e/|b{++}=5.72
 84KR4cE {I12} (1958Ko92); |e/|b{++}=5.66 {I42} (1955We40).
 84KR5cE Theoretical value: |eK/|b{++}=3.44 (allowed transition),
 84KR6cE |eK/|b{++}=4.2 to 4.7 (first-forbidden transition, model dependent,
 84KR7cE see 1970Go44). As discussed by 1970Go44 the values of 1955We40 and
 84KR8cE 1958Ko92 are probably too high because of summation and pileup
 84KR9cE effects. Also from theoretical considerations the lower value of
 84KRxcE 1970Go44 is preferred.
