“…In the experiment described below, a positive sign of the g-factor has been determined: g=0.282(6). This value is in good agreement with the predicted gfactor for the configuration {reds/2 X (1148n, 7 )}19/2 proposed by Bron [2]; gcalcWat~d= +0.29 for g(~ds/2) = 1.38 and g(~ 14Sn, 7-)= -0.10 [3]. In our experiment, which was of the TDPAD type, we used the 113In(c42nT) reaction with 28 MeV :~'s burstsuppression by an internal deflection system has been applied in order to obtain an interval of 1 laS between the bursts.…”

“…The relative intensities of the delayed gamma rays are given in Table 3 a. It should now be observed that this scheme suggests the following intensity relation of delayed gamma rays: [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30](1 + ~) =11.536 +11,438 +I1,1 54.+11.252 =/tot" Since none of the high energy gamma rays can have a higher multipolarity than E3, the conversion electron intensities can be neglected. From Table 3a it is found that:…”

Using the 2~ 3n) reaction with e-particles of about 40 MeV, we have proved by applying nowadays conventional y-ray spectroscopy in-beam technique, that there are two isomeric states in 2~ at the excitation energies 5,161.3 and 3,195.5 keV having the half-lives 71 ___ 3 and 217_+ 5 ns, respectively. These isomeric states have spins and parities 33/2 + and 25/2-and are mainly due to the i{3~2and .-2 -1 113,2 Pl, 2 configurations, respectively. This conclusion is supported by the experimental g-factors of these states being -0.159_+ 0.008 and -0.0676_+0.0011, respectively. It is furthermore shown that the E2 effective neutron charge is the same for E2 transitions from the 33/2 + state in 2~and from the 12 + state in 2~as required by the assumption that the 2~ core is responsible for the total E2 strength of the neutron holes, and that these states are due to the ii-332 and i-2 configura-13:2 tions. The calculated B(E3) values of E3 transitions from isomeric states in 2~ and 2~ agree reasonably well with the experimental values as expected from the assumption that the E3-strength should come from particle coupling to the octupole states of the 2~ core. The energies of the six most well established excited states in 2~ with angular momenta in the region 19/2-33/2 were calculated using empirical single-particle energies, empirical two-particle interactions and angular momentum algebra. The average deviation between experimental and calculated energies is -3 keV and the root mean square deviation 6 keV as compared to the uncertainty _+ 5 keV in the nuclear masses used in the calculation. For the orbits concerned the shell model is thus valid with an extremely high precision. The contribution of effective three-particle interaction in these orbits must consequently be less than about 5 keV.

“…in second column of the table), only a rough estimate of the experimental value gexp is obtained. This procedure has been carried out for the 73keV 3 + state in 13SLa, using as empirical values g(137La; 7/2+), g(~39La; 7/2+), g(~37Ba; 3/2+), g(~39Ce; 3/2 +) and -since no g-factor measurements are available for 5/2 + states in 137'139La or for 1/2 + states in lSVBa or 139Ce g(~41Pr; 5/2 +) and g(129Xe; 1/2 +) 51 [14]. These interactions can be approximately taken into account, if experimental g-factors of adjacent oddmass nuclei are used as empirical values instead of the single-particle values.…”

The magnetic moment of the first excited state in138La

The g-factor of the first excited state in the odd-odd nucleus 138La (E x =73 keV, U= 3 § T~/2=116ns) was measured by the time-differential perturbed angular distribution (TDPAD) method. The result, corrected for Knight shift and diamagnetic shielding, is g= +0.962 +0.016. This value can be fairly well reproduced using the additivity relation for magnetic moments, empirical values for the odd-proton and odd-neutron g-factors, and an experimentally deduced wave function for the 3 + state.
