    Notes: Abstract The angular distributions of the 6.13 MeV γ1 transition in the reaction19F(p, α γ)16O have been measured with improved accuracy at proton energies of 873 keV and 1,374 keV using a Ge(Li) detector. The results can be fitted by Legendre polynom series witha 2=−0,018±0.008;a 4=0.000±0.008 atE p =873 keV anda 2=−0.130±0.005;a 4=+0.004±0.004 atE p =1,374 keV. From the measured Legendre coefficients α1-angular momentum mixing ratios are extracted and compared with the results from (p, α1) and (α1, γ1) correlations.

    Derp 3/2-Analogzustand in51V (1970)

    Notes: Abstract In an investigation ofT=7/2 analogue states in51V the50Ti(p, γ) excitation curve has been measured for proton bombarding energies 1280–1480 keV and 2340–2660 keV. From the (p, γ) resonances 29 new virtual levels in the region of 9316–9510 keV excitation energy in51V were determined. The strong resonance atE p=1 371 keV has been identified as the isobaric analogue state of the51Ti ground state by determining spin and parity of this resonance to be 3/2−. There is no evidence for a strong analogue resonance in51V corresponding to the 1.16 MeV p 1/2 state in51Ti. The γ-decay of the p 3/2 analogue state has been studied by measuring branching ratios and angular distributions of primary γ-transitions with a Ge(Li) detector.M1E2 mixing ratios have been determined for these transitions. The total width of the resonance for γ-decay is found to be Γγ=1.6±0.4 eV. New bound levels in51V have been introduced at 3576, 4651 and 4661 keV excitation energy. TheJ π values of the 3085, 4770, and 4863 keV states are determined to be 5/2−, 5/2−, 3/2−, respectively. The analogue-antianalogueM1 transition strength is found to be considerably reduced compared to the situation ins-d shell nuclei.

    Notes: Abstract The proton capture cross sections for the reaction63Cu(p, γi)64Zn leading to several resolved states in the64Zn nucleus have been measured forE p =6.5–11.0 MeV. The excitation functions have been reproduced by the combined CN and DSD models. The extracted spectroscopic factors compared with those derived from the stripping reaction are found to show a distinct correlation.

    Study of the ground state doublet in57Fe (1973)

    Notes: Abstract The56Fe(d,p)57Fe reaction has been studied at an incident energy of about 10 MeV. The ground state doublet of57Fe has been resolved using the Heidelberg Q 3 D magnetic spectrograph and the Minnesota split-pole spectrograph. The ratio of the spectroscopic strengths (2J+1)S for the transitions to the first excited state at 14.4 keV excitation energy (J π=3/2−) and the ground state (J π=1/2−) has been determined to be 5.80±0.5. This number is of special interest with respect to a possible deformation of the nucleus57Fe and in connection with the corresponding analogue resonances in57Co.

    Proton-neutron quasiparticle RPA and charge-changing transitions (1989)

    Notes: Abstract General formulae for a proton-neutron QRPA calculation are presented. All terms in the RPA order are retained, and no specific assumptions on the residual interaction and one-body charge-changing transitions are made. QRPA phonon correlations are introduced in first-order perturbation for quasiparticle transitions from odd-mass and odd-odd parent nuclei.

    Notes: Abstract Beta decay properties of nuclei far from stability are of decisive importance for the understanding of the element synthesis in the universe and the determination of the age of the universe by means of cosmochronometers. A new large scale microscopic calculation ofβ −-decay half-lives up to the neutron drip line is presented. This new approach uses the proton-neutron quasiparticle random phase approximation with a Gamow-Teller residual interaction.

    Spin assignments by a high spin selective heavy ion reaction (1973)

    Notes: Abstract The reaction12C(14N,d)24Mg is investigated atE Lab=52 MeV by means or a multigap magnetic spectrograph. Angular distributions of levels between 6.00 and 20.21 MeV are measured using nuclear track emulsions. By quantitative analysis of the angular distributions (FRDWBA- and Hauser-Feshbach calculations), the reaction is shown to proceed almost completely via compound mechanism. The reaction is applied for selective excitation of high spin states in24Mg. Evidence is given by this example that under suitably chosen conditions a complex heavy ion reaction can be a powerful means for spin assignments at high excitation energies.

    Notes: Abstract The nuclear matrix elements of the 0ν ββ decay of76Ge,82Se,100Mo,128,130Te,136Xe and150Nd are calculated in the proton-neutron quasiparticle RPA with theG-matrix of the Paris potential. It is shown that the matrix elements are not sensitive to details of nuclear structure, in contrast to the 2ν ββ decay. We investigate effects of ground-state correlations and those of short-range correlations on the suppression of the nuclear matrix elements. We also discuss effective values of the neutrino mass which are deduced from experimental 0ν ββ decay half-lives.

    Effects of ground-state correlations on 2νββ decay rates and limitations of the QRPA approach (1989)

    Notes: Abstract Half-lives of the 2νββ decay are calculated in the proton-neutron QRPA for76Ge,82Se,100Mo,128,130Te,136Xe and150Nd. The strength of the particle-particle interaction, which plays a decisive role for a reliable evaluation of the half-lives, is determined from a QRPA calculation of singleβ + decays. The 2ν decay rates calculated with the interaction strength fitted in this way are strongly suppressed and found to be consistent with the existing experimental data. Effects of the ground-state correlations on the suppression are investigated. On the other hand, the present calculation indicates limitations of the QRPA approach.
