82SE c Based on XUNDL dataset from 2004Ga44
82SE2c compiled by J. Roediger and B. Singh (McMaster), September 10, 2004
82SE C 2004Ga44:
82SE2c 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.
82SE9c 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 1975Kr08.
82SE2C Tentative levels, at 3705, 4566, have not been confirmed.
82SE C Others:
82SE C 1975Kr08: 82SE(N,P), fission products, chemical
82SE2C separation, 82AS activity from 82GE separation.
82SE3C GE(LI), Measured EG, RI, GG.
82SE C 1972DE43: 235U(n,F), measured EG, IG, G(T).
82SE2C Determined T1/2(82AS)=22.6 S 14 from 656G(T)
82SE C 1970Va31: 82SE(N,P), GE(LI) FWHM=3.5 KEV at 1.33 MEV,
82SE2C SI(LI), NAI(TL), and plastic scin.
82SE3C Measured EB, IB, EG, RI, BG, GG coin.
82SE4C Both 82AS isotopes were produced and some of the transition assignments
82SE5C could not be resolved.
