 23NA c  2017Ma18: {+23}Mg was produced from {+23}Na(p,n) reaction, E=15,30 MeV;
 23NA2c  After mass separation, {+23}Mg nuclides (contaminated only by {+23}Na)
 23NA3c  were transported to the yield station and deposited on a Mylar tape (50
 23NA4c  |mm thickness and 1.25 cm width) for |b particle and |g ray detection
 23NA5c  by plastic scintillator and HPGe detectors. The plastic scintillator
 23NA6c  was read out by two photomultipliers (PMs). The coincidence signals of
 23NA7c  these PMs were used to count the |b+ particles and to trigger the
 23NA8c  data acquisition of the HPGe detector. Measured {+23}Mg half-life from
 23NA9c  |b(t), 440|g absolute emission probability, and deduced
 23NAac  super-allowed |b-transition branch g.s. to g.s. from feedings of
 23NAbc  {+23}Na excited states.
 23NA c  1974Ma41: {+23}Mg produced from {+23}Na(p,n), Ep=10~MeV, reaction.
 23NA2c  Measured |g-ray branching, beta feedings.
