    Das magnetische Moment des 2,083 MeV-Zwei-Protonen-Niveaus des gerade-gerade-Kerns Ce140 (1963)

    Notes: Abstract The nuclearg-factor of the 2·083 MeV-state of Ce140 has been determined as:g=1·11±0·04 This value suggests the interpretation of the level as the (g7/2,d5/2)4 two proton shell model configuration. The investigation implies an integral measurement as well as a time dependent differential measurement (spin rotation method) of the rotation of the 329 keV-487 keVγγ-angular correlation in strong external magnetic fields. Liquid sources of lanthanum nitrate solved in 3n HNO3 were used in these experiments. Some cerium (IV)nitrate was added to make sure that the 4f;-electronic shell remained empty after theβ −-decay. This prevented paramagnetic effects. Additional runs were performed without adding cerium (IV)nitrate and finally by using liquid sources of lanthanum chloride solved in 2n HCl with some iron (II)-chloride added. It was expected that the Fe++ ions would reduce the primarily formed Ce++++ ions into the Ce+++ state. The Ce+++ shell is paramagnetic and enlarges the effective magnetic field at the position of the nucleus by about 36%. As no definitely faster rotation could be observed, one has to conclude that the ion reaction Ce+++++Fe++⇒Ce++++Fe+++ takes more than about 10−8s. The half life of the 2·083 MeV state has been redeterminded asT 1/2=(3·41±0·04)·10−9s. Differential measurements of the angular correlation of the 329 keV-487 keV cascade as a function of the time delay showed that perturbations by internal fields were very small. The coefficientsA 2 andA 4 of the angular correlation and the attenuation parameterλ 2 were determined from measurements with sources of the first type as:A 2=−0·105±0·003A 4=−0·001±0·002 andλ 2=(0·0065±0·0040)·109S−1=(0·032±0·020)·λ A comparison with the theoretical coefficients of a (3-4-2)-cascade shows that the multipolarity of the 329 keV radiation is a mixture of 99·83%M1 and (0·17±0·03) %E2.

    Das gyromagnetische Verhältnis des 2+-Rotationsniveaus von Hf178 und weitere Untersuchungen zum Zerfall von W178 (1962)

    Notes: Abstract The nuclearg-factor of the 2+ rotational state of Hf178 was determined by a measurement of the rotation of the angular correlation between the gamma-group of ∼1350 keV and the 93 keV radiation in an external magnetic field of 49550 gauss. The result is: $$g_R = + 0 \cdot 356 \pm 0 \cdot 035.$$ Liquid sources of 21 days W178 (ammoniumtungstate in aqueous solution) in equilibrium with 9.3 min Ta178 have been used for these measurements. Differential angular correlation measurements showed the existence of a strong time dependent attenuation. The observed attenuation parameters are: $$\begin{gathered} \lambda _2 /\lambda = 0 \cdot 85 \pm 0 \cdot 23 \hfill \\ \lambda _4 /\lambda = 0 \cdot 74 \pm 0 \cdot 10. \hfill \\ \end{gathered} $$ The true coefficients of the angular correlation between the gamma-group of ∼1350 keV and the 93 keV radiation were derived as: $$\begin{gathered} A_2 = + 0 \cdot 330 \pm 0 \cdot 047 \hfill \\ A_4 = 0 \cdot 990 \pm 0 \cdot 060. \hfill \\ \end{gathered} $$ As they are substantially larger than previously published values a reinterpretation of the correlation function is given. The half-life of the 93 keV state was found to be: $$T_{\tfrac{1}{2}} = (1 \cdot 49 \pm 0 \cdot 05) \cdot 10^{ - 9} \sec $$ in good agreement with the coulomb excitation data.

    Die magnetischen Momente der 5−-Niveaus von Sn118 und Sn120 (1962)

    Notes: Abstract The rotations ofγγ-angular correlations in strong external magnetic fields were observed in the decay of 5.1h Sb118 and 5.8d Sb120. Values of the gyromagnetic ratios of the 5− two particle states of Sn118 and Sn120 were derived. In the case of 5.1 hours Sb118 the rotation of the 254 keV-1.221 MeVγγ-angular correlation in a field of 40950 Gauss was measured as $$\omega _L \cdot \tau = 0 \cdot 417 \pm 0 \cdot 038,$$ , and theg-factor of the 5− state was derived as $$g = - 0 \cdot 068 \pm 0 \cdot 007.$$ . This value is correct under the assumption that the rotation in the 4+ state is negligible. The half life of this state was found to be $$T_{\tfrac{1}{2}} \underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } 7 \cdot 10^{ - 10} \sec .$$ In the case of 5.8d Sb120 the rotation of the 200 keV-90 keVγγ-angular correlation in a field of 53200 Gauss was found to be $$\omega _L \cdot \tau = 0 \cdot 150 \pm 0 \cdot 020,$$ and theg-factor of the 5− state was derived as $$g = - 0 \cdot 074 \pm 0 \cdot 010.$$ The evaluation implies a small correction for the Compton-underground of the high energyγ-transitions. It is assumed that the rotation in the 4+ state is negligible. The half life of the 4+ state was found to be $$T_{\tfrac{1}{2}} \underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{ \leqslant } 6 \cdot 10^{ - 10} \sec .$$ The half lives of the 5− states of Sn118 and Sn120 were determined as $$T_{\tfrac{1}{2}} = \left( {21 \cdot 7 \pm 0 \cdot 2} \right) \cdot 10^{ - 9} \sec $$ and $$T_{\tfrac{1}{2}} = \left( {5 \cdot 53 \pm 0 \cdot 06} \right) \cdot 10^{ - 9} \sec $$ respectively. Differential angular correlation measurements proved that attenuations in the 5− states by internal fields were very small for the liquid sources used in these experiments. The results for the gyromagnetic ratios of the 5− states are consistent with the theoretical interpretation of these levels as mainly (h 11/2,s 1/2) two-neutron-configurations.

    Notes: Abstract The rotation of the angular correlation between theγ-group at about 820 keV and the 80 keV radiation in the decay of Tm168 has been observed in an external magnetic field of 20300 gauss. The result:ω R·τ=0,485±0,051 yields for theg R -factor of the 80 keV state of Er168:g R =+0,25±0,03. The evaluation includes a paramagnetic correction factor of:β=7,26, (B eff=β·B ext). The angular correlation is slightly attenuated by internal fields. For a liquid source of Tm (NO3)3 solved in 3 n HNO3, a measurement of the differential angular correlation as a function of the delay time gave:λ 2=(5,8±2,9)·107sec−1, assumingA 2(t)=A 2(0)·e −λ 2·t. The half life of the 80 keV state was found to be:T 1/2=(1,92±0,04)·10−9sec in agreement with earlier measurements.
