50CR c 1994Ha43: {+50}Mn source was produced in (p,n) reaction at the TASCC
50CR2c facility. Measured E|g, I|g, |g(t), with a HPGe detector tagged by
50CR3c positron events measured by two thin plastic scintillators. See also
50CR4c 1993HaZT
50CR c Several theoretical and systematic studies, e.g. 2009Ha12, have been
50CR2c made on the super-allowed |b decay of {+50}Mn g.s. and isospin states.
50CR3c Consult Nuclear Science References (NSR) database for these.
50CR c 1965Fr08: measured half-life, and deduced log {Ift} value for the
50CR2c decay to the g.s. of {+50}Cr.

50CR cG E,RI$from 1994Ha43. A 3045|g was also assigned to {+50m}Mn |b{++}
50CR2cG decay; from comparison of pure {+50m}Mn and mixed {+50}Mn and
50CR3cG {+50m}Mn samples 1994Ha43 concluded that this is a doublet and up to
50CR4cG 60% of the peak area in the mixed sample spectra may be attributed to
50CR5cG a nonanalog decay branch in {+50}Mn.
