82SE c Isotopes of {+82}As were produced via neutron-induced fission of a
82SE2c {+235}U target. The desired isotope was then ionized by plasma
82SE3c ionization and mass seperated before being collected on mylar tape in
82SE4c front of the detector system. Tape movements were used in order to
82SE5c minimize contributions from possible contaminations by long lived
82SE6c nuclides. In a second experiment of the same reaction, |g-ray
82SE7c multi-spectrum scaling was performed where tape movements were
82SE8c followed by seven groups of data taken with the beam deflected.
82SE c Measured E|g, I|g, |g|g, I|b, |b|g (coin) using standard coaxial HPGe
82SE2c detectors, while a Low Energy Photon Ge detector (LEP) was used as a
82SE3c |b detector.
82SE C Decay scheme is in general agreement with earlier work of
82SE2C 1975Kr08: 82SE(N,P), fission product, chemical
82SE3C separation. Measured EG, IG,GG; GE(LI)
82SE C Others:
82SE C 1970Va31: 82SE(N,P). Measured EB, IB, EG, RI, BG, GG;
82SE2C GE(LI) FWHM=3.5 KEV at 1.33 MEV, SI(LI), NAI(TL), and plastic scin.
82SE C 1970KA04: 82SE(N,P). Measured EG, IG, EB, GG, BG. Measured T1/2(82AS)=
82SE2C 13.7 S 8 from 342G(T).
82SE3C In all experiments both 82AS isotopes are produced. The G's
82SE2C of the two decays are separated by 1975Kr08 by comparing the
82SE3C relative intensities of sources produced by (N,P) and by
82SE4C fission. Intensities are quoted as shown in the drawing
82SE5C of 1975Kr08.
