Concerning the Quadrupole - Quadrupole Interaction
We address some properties of the quadrupole-quadrupole (Q · Q) interaction in nuclear studies. We first consider how to restore SU (3) symmetry even though we use only coordinate and not momentum terms. Using the Hamil
متن کاملFully Batch-fabricated Linear Quadrupole Mass Filters
We report the design, fabrication, and characterization of a fully batch-fabricated linear quadrupole mass filter. The device demonstrates for the first time, a microfabricated quadrupole mass filter that doesn’t require any post-fabrication electrode assembly. Utilizing a design with non-conventional square electrodes, a 30 mm quadrupole with an effective electrode diameter of ~1.7 mm, and int...
متن کاملThe Onset of Chaos with a Quadrupole–quadrupole Interaction
The transition from order to chaos in atomic nuclei has been studied analytically and numerically using a quadrupole–quadrupole residual interaction. This interaction leads to chaotic behaviour, but the critical energy E C ≃ 12.6 MeV, corresponding to the onset of chaos, is higher than that of the experimental one.
متن کاملThe Isovector Quadrupole-Quadrupole Interaction Used in Shell Model Calculations
An interaction −χQ ·Q(1+B~τ(1) · ~τ(2)) is used in a shell model calculation for 10Be. Whereas for B = 0 the 21 state is two-fold degenerate, introducing a negative B causes an ‘isovector’ 2+ state to come down to zero energy at B = −0.67 and an S = 1 L = 1 triplet (J = 0+, 1+, 2+) to come down to zero energy at B = −0.73. These are undesirable properties, but a large negative B is apparently n...
متن کاملQuadrupole - quadrupole interaction calculations which include N = 2 mixing
We carry out a study of the study of the Q · Q interaction in a model space which consists of several nucleons in an open shell and all 2¯ hω excitations. Xo 2 Q · Q, where for t=1 we get the 'accepted strength'. In the 0p space, the spectrum would scale with t. In this space, the 2 + 1 and 2 + 2 states of 10 Be are degenerate, as are the [330] and [411] sets of J = 0 + , 1 + and 2 + triplets. ...
