Evidence for a (1f 7/2 ) 3 3/2 state in 49 23 V 26

Autor: L.Th.M. Ornstein, N.F. Verster, A.H. Wapstra, G.J. Nijgh, R.H. Nussbaum

Publikováno v: Physica. 20:165-168

Synopsis Gamma transitions of 63 ± 1 keV (15 ± 2%), 89 ± 1 keV (30 ± 4%) and 150 ± 2 keV (14 ± 2%) (intensities relative to total positon activity) were found in the decay of 49 Cr by means of a single channel NaI-scintillation spectrometer. Fr

The decay of 15Ti and the nuclear levels in 51V

Autor: A.H. Wapstra, M.J. Sterk, R.H. Nussbaum

Publikováno v: Physica. 21:441-445

Synopsis The decay of 5.8 min. 51Ti has been investigated by means of β- and γ-scintillation spectrometers combined with coincidence counting. It is found that the main β−-spectrum has a maximum energy of 2.17 ± 0.04 MeV and that it is in coinc

On the radioactive decay of 112Pd and 112Ag

Autor: H. Cerfontain, N.F. Verster, R.H. Nussbaum, A.H. Wapstra

Publikováno v: Physica. 19:385-390

Synopsis The radioactive decay of 112Pd → 112Ag → 112Cd has been investigated both with a βγ-coincidence apparatus and with a single channel Nal (Tl) scintillation spectrometer. A short description of the main features of the instruments is giv

Nuclear levels in 60 Ni from the decay of 60 Cu

Autor: R. Van Lieshout, R.H. Nussbaum, L.Th.M. Ornstein, G.J. Nijgh, A.H. Wapstra, F.E.L. Ten Haaf, N.F. Verster

Publikováno v: Physica. 20:555-570

Synopsis Radiations from 60 Cu have been investigated by means of a single channel NaI-scintillation spectrometer and a magnetic lens type β -ray spectrometer. Moreover, γ — γ coincidences using two single channel scintillation spectrometers hav

Internal conversion in Fe57 from the Mössbauer effect in iron

Autor: R.M. Housley, R.H. Nussbaum

Publikováno v: Nuclear Physics. 68:145-152

The conversion coefficient of the 14.4 keV Mossbauer transition in Fe57 was determined from the effective nuclear resonance cross section of a thin natural iron foil placed in a saturating magnetic field. Near natural line widths were obtained with a

Impurity lattice dynamics of Fe in Cr from precision Mössbauer fraction measurements

Autor: D.G. Howard, B.F. Brace, R.H. Nussbaum

Publikováno v: Physics Letters A. 43:336-338

Precision 〈x2〉-values and their anharmonicity been measured for 57Fe in Cr between 80 K and 600 K. At 294 K. ƒ = 0.798 ± 0.005 . A theoretical analysis based upon Cr neutron scattering data yields 0.8 for the impurity/host force constant ratio.
