Electromagnetic Structure of the Trinucleons

The electromagnetic form factors of the trinucleons 3H and 3He are calculated with wave functions obtained with the Argonne AV18 two-nucleon and Urbana IX three-nucleon interactions. Full account is taken of the two-body currents required by current conservation with the AV18 interaction as well as those associated with N-Delta transition currents and the currents of Delta resonance components in the wave functions. Explicit three-nucleon current operators associated with the two-pion exchange three-nucleon interaction arising from irreducible S-wave pion-nucleon scattering is constructed and shown to have very little effect on the calculated magnetic form factors. The calculated magnetic form factor of 3H, and charge form factors of both 3H and 3He are in satisfactory agreement with the experimental data. However, the position of the zero in the magnetic form factor of 3He is slightly underpredicted.Comment: 27 pages RevTex file, 19 PostScript figures, submitted to Phys. Rev.

Nucleon form factors in the canonically quantized Skyrme model

The explicit expressions for the electric, magnetic, axial and induced pseudoscalar form factors of the nucleons are derived in the {\it ab initio} quantized Skyrme model. The canonical quantization procedure ensures the existence of stable soliton solutions with good quantum numbers. The form factors are derived for representations of arbitrary dimension of the SU(2) group. After fixing the two parameters of the model, $f_\pi$ and $e$, by the empirical mass and electric mean square radius of the proton, the calculated electric and magnetic form factors are fairly close to the empirical ones, whereas the the axial and induced pseudoscalar form factors fall off too slowly with momentum transfer.Comment: 14pp including figure

The Factors Affecting Tourist Visits at Owabong Waterpark in Bojongsari Sub-district of Purbalingga

This research aimed to determine the effect of income, travel cost, distance and visitor age on the number of tourist visit to Owabong Waterpark. This research is a survey research to visitors of Owabong Waterpark using accidental sampling method. Qualitative and quantitative data was derived questionnaire based interview technique. This research used multiple linear regression analysis with double log model. The result indicated that income had a positive effect on tourist visits at Owabong Waterpark. Travel cost and distance have insignificant effect on tourist visits at Owabong Waterpark. Age had insignificant effect on tourist visits at Owabong Waterpark. The implication of this research for the management of Owabong Waterpark is to continously improve the existing facilities and infrastructures to maintain the quality of tourist attraction, always innovate various vehicles attracting the visitors, conduct promotions such as discounted ticket to reach all income groups, conduct more vigorous promotions, especially in social media to be better known by the community outside Purbalingga so that Owabong Waterpark is not only visited by local tourists, but also foreign tourists

The Breathing Modes of the B=2B=2 Skyrmion and the Spin-Orbit Interaction

The coupling of the breathing and rotational modes of the skyrmion-skyrmion system leads to a nucleon-nucleon spin-orbit interaction of short range, as well as to spin-orbit potentials for the transitions $NN \to N(1440)N$, $NN \to NN(1440)$ and $NN \to N(1440)N(1440)$. The longest range behaviour of these spin-orbit potentials is calculated in closed form.Comment: Latex, figures not include

The Quantum Skyrmion in Representations of General Dimension

The representations of general dimension are constructed for the $SU(2)$ Skyrme model, treated quantum mechanically {\it ab initio. } This quantum Skyrme model has a negative mass term correction, that is not present in the classical Hamiltonian. The magnitude of the quantum mechanical mass correction increases with the dimension of the representation of the $SU(2)$ group. In the case of a 5-dimensional representation it is possible to obtain satisfactory predictions for the nucleon mass with the empirical value for the pion decay constant.Comment: Plain latex, 15 page
