73GE2c sodium arsenate onto a 1 mg/cm{+2} melinex sheet. |g and x rays were
73GE3c detected with a NaI(Tl) crystal and conversion electrons were detected

73GE6cL measurements with a 3% uncertainty included due to calibration of the
73GE7cL delay as indicated by the authors; 1970Ky01 give a weighted average of
