Abstract
According to the nuclear Table(1) by P. Raghavan, the measurement of the electric quadrupole moment Q(b) for the majority of elements can be indicated by one unique value, concerning a specific method. For example, for the 3Li7 we have:
- 3Li7 Q(b) Method
- -0.0406ST MB,R
- -0.0370(8) CIAN
- -0.041(6)ST OD,OL
- -0.059(8) OL
- -0.040(11) CER
But the excited nucleus 8O18 has two different values of Q(b). For example, the method CER supplies two different values:
- 8O18 Q(b) Method
- -0.073(27) or -0.045(28) CER
It is not an error due to a lack of accuracy in the method. In reality -0.073(27) and -0.045(28) are two different and independent measurements, since one has an error ?0.027, and the other an error ?0.028. It is well to emphasize that from the current Nuclear Physics it makes no sense to think about the possibility of two or three different nuclear structures for the isotopes of 8O18, and therefore such a problem even does not exist in Nuclear Theory, and so the question is not taken into consideration by the nuclear physicists. In the whole table, from the 1H2 to the 99Es254, the same happens with only the following elements: 12Mg26, 14Si30, 14Si32, 16S32, 30Zn64, 32Ge70, 42Mo94, 42Mo96, 42Mo100, 44Ru98, 44Ru100, 44Ru102, 44Ru104, 46Pd104, 46Pd106, 46Pd108, 46Pd110, 48Cd116, 50Sn122, 56Ba134, 56Ba136, 56Ba138, 58Ce142, 78Pt198, 80Hg198, 80Hg200, 80Hg202, 80Hg204. In particular, the 50Sn122 has an interesting value of quadrupole moment: -0.28 = Q(b) = +0.14, by the method CER. Here we will try to understand why the experiments detect two different values of quadrupole moment.
