95MO C Evaluation by ^ R.G. Helmer, July 1998 including some general
95MO2C comments from previous evaluation (1993Bu08). This evaluation was
95MO3C done as part of a collaboration of evaluators from Laboratoire
95MO4C National Henri Becquerel (LNHB) in France; Physikalisch-Technische
95MO5C Bundesanstalt (PTB) in Germany; HMS Sultan and AEA Technology in the
95MO6C United Kingdom; Khlopin Radium Institute (KRI) in Russia; Centro de
95MO7C Investigaciones Energeticas, Medioambientales, y Tecnologicas
95MO8C (^CIEMAT) and Universidad Nacional a Distancia (^UNED) in Spain; and
95MO9C Brookhaven National Laboratory (^BNL), Lawrence Berkeley National
95MOaC Laboratory (^LBNL), and Idaho National Engineering and Environmental
95MObC Laboratory (^INEEL) in the United States.
95MO C Measurements include: |b{+-}'s and ce's (mag spect, pc, Si)
95MO2C (1963La06); see {+95}Zr |b{+-} decay for details (1974An22); |g's for
95MO3C a mixed 35-day and 3.61-d {+95}Nb source and a mixed {+95}Zr and
95MO4C {+95}Nb source, Compton-suppressed Ge(Li), lead attenuator to enhance
95MO5C high-energy |g's (1976Ho04); |g's, Ge(Li), energy difference method
95MO6C (1979Gr01).
95MO C For previous evaluation, see 1991BaZS.
95MO CB $The unobserved |b transitions to the 786- and 820-keV states are
95MO2CB 4{+th} forbidden and unique 2{+nd} forbidden, respectively. From the
95MO3CB log| {Ift} systematics of 1998Si17, the feeding of these levels are
95MO4CB expected to be <1.0|*10{+-15}% and <1.0|*10{+-8}%, respectively, and,
95MO5CB therefore, are completely negligible.
