Fine structure in the decay of deformed proton emitters: nonadiabatic approach
The coupled-channel Schrodinger equation with outgoing wave boundary conditions is employed to study the fine structure seen in the proton decay of deformed even- N, odd- Z rare earth nuclei 131Eu and 141Ho. Experimental lifetimes and proton-decay branching ratios are reproduced. Variations with the standard adiabatic theory are discussed.
متن کاملProton decay: spectroscopic probe beyond the proton drip line
Proton decay has been transformed in recent years from an exotic phenomenon into a powerful spectroscopic tool. The frontiers of experimental and theoretical proton-decay studies will be reviewed. Different aspects of proton decay will be illustrated with recent results on the deformed proton emitter 135Tb, the odd–odd deformed proton emitter 130Eu, the complex fine structure in the odd–odd 146...
متن کاملFission and ternary cluster decay of hyper - deformed 56 Ni
Coincidences between two heavy fragments have been measured from the fission of Ni compound nuclei formed in the S + Mg reaction at Elab( S) = 165.4 MeV. A unique experimental set-up consisting of two large-area position-sensitive (x, y) gas detector telescopes has been used allowing the complete determination of the observed fragments and their momentum vectors. In addition to binary fission e...
متن کاملStellar weak decay rates in neutron-deficient medium-mass nuclei
Weak decay rates under stellar density and temperature conditions holding at the rapid proton-capture process are studied in neutron-deficient medium-mass waiting-point nuclei extending from Ni up to Sn. Neighboring isotopes to these waiting-point nuclei are also included in the analysis. The nuclear structure part of the problem is described within a deformed Skyrme Hartree-Fock + BCS + quasip...
متن کاملDiproton decay of nuclei on the proton drip line.
The process of direct two-proton decay of nuclei with Z 22-28 on the proton drip line is considered. On the basis of new Od3t2 Offi2 -shell-model mass extrapolations, '9Ti, 42Cr, 45Fe, Ni, and Ni are found to be bound to single-proton decay but unbound to two-proton decay. New estimates of the spectroscopic factors and lifetimes have been made. The decays of Ti, Fe, and Ni are found to be promi...
