Orientation of199mHg by optical pumping detected by γ-radiation anisotropy

Abstract

199mHg was produced and mass separated at the ISOLDE facility (CERN). Nuclear orientation achieved by optical pumping via the resonance line 6s 2 1 S 0→6s6p 3 P 1,λ=2537Å 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−).

Maximum anisotropies of 35% (2,8%) were found in the M4 (E2) transition. A Zeeman scanning of the3 P 1 state yielded the positions ofF=13/2 and theF=15/2 hfs components relative to the reference isotope204Hg at 15.13 (15) GHz and −2.86 (15) GHz respectively. Isotopic shift and the quadrupole interaction constant were deduced from these values using the knownA factor.δv 199m/2O4=v 2O4−v 199m=12.20 (16) GHzB=−0.86 (25) GHz.

From theB factor the spectroscopic quadrupolment was calculated asQ s =1.54 (44) barn.
