(Dated: May 3, 2004) Abstract It is shown how a bare three–nucleon force is incorporated into the formalism of the effective interaction approach for hyperspherical harmonics. As a practical example we calculate the ground state properties of 3H and 3He using the Argonne V18 nucleon–nucleon potential and the Urbana IX three–nucleon force. A very good convergence of binding energies and matter r...

We present a detailed comparison between the first order Stark-effect induced Gailitis resonance in e+ + H (n = 2) and the second order Stark-effect induced resonance in e + Ps (n = 1). Common characteristics as well as differences of these resonances will be identified. These results will be used to assess the presence of Gailitis resonances in the scattering of proton on the ground state of 7...

We find that the excitation energies of single analog states for odd-even nuclei in the f7/2 shell with J=j=7/2 − and the J=0 double analog states in the even-even nuclei are well described by the formulas E∗ (j, T + 1) = b(T + X) and E∗ (0, T + 2) = 2b(T + X + 0.5),respectively, where T =| N − Z | /2 is usually the ground state isospin. It is remarkable to note that the parameter X accounts fo...

Quite detailed theoretical description of superfluid 3He is possible on length scales that are much larger than the atomic scale. We discuss weak links between two bulk states of 3He-B. The current through the weak link is determined by the bound states at the link. The bound state energies are spin split depending on the order parameters in the bulk. As a result, unusual current–phase relation...

Photochemical reactions may be classified as adiabatic or as diabatic whether the chemical change occurs on the same potential energy surface or not. In the adiabatic cases deexcitation occurs either in the reactant (I) or in the product (II) while in the diabatic case it occurs in between them (III). The potential energy surfaces of polyatomic systems are discussed in relation to photochemistr...

It now appears phenomenologically that the third family may be essentially different from the first two. Particularly the high value of the top quark mass suggests a special role. In the standard model all three families are treated similarly [becoming exactly the same at asymptotically high energies] so I need to extend the model to accommodate the goal of a really different third family. In t...

Allyl phenyl ether has an absorption band in the ultraviolet region (l o 400 nm); therefore, irradiation with few-optical-cycle ultraviolet pulses (l = 360–440 nm) causes a transition to the ultraviolet band, which leads to an electronic state and a photo-Claisen rearrangement (radical reaction) in the electronic excited state. However, the reaction scheme of allyl phenyl ether under irradiatio...

Neutrino reaction cross-sections, (ν µ , µ −), (ν e , e −), µ-capture and photoab-sorption rates on 12 C are computed within a large-basis shell-model framework , which included excitations up to 4¯ hω. When ground-state correlations are included with an open p-shell the predictions of the calculations are in reasonable agreement with most of the experimental results for these reactions. Woods-...
