Re-evaluating reaction rates relevant to nova nucleosynthesis from a nuclear structure perspective
Conventionally, reaction rates relevant to nova nucleosynthesis are determined by performing the relevant proton capture reactions directly for stable species, or as has become possible more recently in invers...

New level information on Z = 51 isotopes, 111Sb60 and 134,135Sb83,84
New data for low-spin low-energy levels in 111,134,135Sb are presented. The observed structures are compared to shell-model calculations. The monopole shifts for the d 5/2 and g ...

Recoil decay tagging study of 146Tm
Gamma-rays from the odd-odd transitional proton-emitting nucleus 146Tm have been observed using the recoil-decay tagging technique. A rotational band similar to the h 11/2 decoupled band i...

Investigating the rp-process with the Canadian Penning trap mass spectrometer
The Canadian Penning trap (CPT) mass spectrometer at the Argonne National Laboratory makes precise mass measurements of nuclides with short half-lives. Since the previous ENAM conference, many significant modi...

Particle-core coupling in the transitional proton emitters 145,146,147Tm
Excited states in 3 transitional proton emitters 145,146,147Tm were studied using the Gammasphere Ge array coupled with the Argonne Fragment Mass Analyzer. The 147Tm level scheme was extended and the unfavored si...

New results on proton emission from odd-odd nuclei
78Kr beams were used to bombard 58Ni, 92Mo and 96Ru, producing three new, odd-odd, proton-emitting isotopes, 130Eu, 164mIr and 170Au. Preliminary experimental and theoretical results will be...

Rotational bands in the proton emitters 131Eu and 141Ho
Proton-decay studies led in recent years to the observation of about 20 new proton emitters. Among others, first two cases of highly deformed proton emitters, namely 131Eu and 141Ho, were reported [1]. Also, the ...

Single-particle and three-quasiparticle cluster states in the light Sn and Sb nuclides
New low energy, low spin levels in 107Sn, 109Sn, and 109Sb have been identified following beta decay of the respective parents. All three experiments were conducted at the ATLAS accelerator facility of Argonne Na...

Population of the 168-keV first excited state in 103Sn in the alpha decay of 107Te
There has been considerable interest in the structure of the light odd-mass Sn nuclides as the states observed there reflect the interactions between valence d 5/2 and g

Binary and Ternary Fission Yields of 252Cf
The spontaneous fission of 252 Cf has been studied via γ — γ — γ coincidence and γ —γ-light charged particle coincidence with Gammasphere. The yields of correlated Mo — Ba pairs in binary fission ...

Masses and Proton Separation Energies Obtained from Q α and Q p Measurements
For many nuclei beyond the proton drip line in the Z > 72, N > 82 region, both proton and α emission are energetically allowed. In the case of some proton emitters, there are α-decay chains emanating from both pa...
