Decay properties of neutron deficient Kr isotopes
The decay properties of the neutron deficient isotopes73–77Kr and73–76Br have been studied at the ISOLDE facility at CERN. The total decay energiesQ, as determined fromβ + singles orβ + -γ coincidence measurements, are compared with mass formulae.
Orientation of199mHg by optical pumping detected by ?-radiation anisotropy
199mHg was produced and mass separated at the ISOLDE facility (CERN). Nuclear orientation achieved by optical pumping via the resonance line 6s21S0→6s6p3P1,λ=2537A was monitored by means of the anisotropy of theγ-radiation emitted in the cascade199mHg(I=13/2+) $${}^{199m}Hg(I = 13/2^ + )\xrightarrow[{M4}]{}{}^{199*}Hg(I = 5/2^ - )\xrightarrow[{E2}]{}{}^{199}Hg(I = 1/2^ - ).$$ 199*Hg(I=5/2−)199Hg(I=1/2−).
