[en] The three-Component-Deck-Model (TCDDM) is applied to the (ΛK) channel in pp reaction. The results are concluded to be very satisfatory and take account of the experience. Advantage is taken of the fact that spin-structure is the same as (Nπ) channel which has been in a previous paper. (Author)

[en] The states of ⁹⁶Ru are investigated in terms of the a α+ core structure. The ground state band of the α+⁹²Mo system is obtained through a local cluster-core potential which includes a fixed set of parameters employed in other mass regions. The calculated spectrum gives a good general description of the experimental ⁹⁶Ru levels. The reduced α-widths, B(E2) transition rates and rms intercluster separations are determined for the members of the ground state band. The results show that the model can reproduce the order of magnitude of the experimental B(E2) values without the use of effective charges and indicate that the first members of the ground state band present a stronger α-cluster character. Predictions concerning a negative parity band of the α+⁹²Mo system are also shown.

[en] The alpha-cluster model is used to investigate the α+⁸⁸Sr structure in the states of ⁹²Zr. The ground state band of the α+⁸⁸Sr system is calculated with a local cluster-core potential. A set of parameter values applied in previous α+core calculations is used for the α+⁸⁸Sr potential, giving a good account of the experimental spectrum. The model can reproduce correctly the order of magnitude of the experimental B(E2) values without the use of effective charges. The rms intercluster separations indicate that the first members of the ground state band present a stronger α-cluster character. Predictions concerning a negative parity band of the α+⁸⁸Sr system are also shown.

[en] The α+core structure is investigated in the nuclei ⁹⁰Sr and ⁹⁸Pd. The ground state bands of the α+⁸⁶Kr and α+⁹⁴Ru systems were calculated with a local cluster-core potential, where only the radial parameter is variable. The calculated spectra give a good general description of the experimental ⁹⁰Sr and ⁹⁸Pd levels. The reduced α-widths, B(E2) transition rates and rms intercluster separations are determined for the ground state bands of the two nuclei. The calculations reproduce correctly the order of magnitude of the experimental B(E2) values of ⁹⁰Sr without the use of effective charges and indicate that the first members of the ground state band of ⁹⁸Pd present a stronger α-cluster character. Predictions concerning a negative parity band of the α+⁹⁴Ru system are also shown.
