Abstract

A chain of four odd-odd proton emitters ( ¹⁴⁶Tm, ¹⁵⁰Lu, ¹⁵⁶Ta and ¹⁶⁰Re ) has been established from Z=69–75, representing the heaviest region in which proton radioactivity has been identified. This also clearly shows that the proton drip-line has been crossed up to Z=75. The results indicate that there is a reversal in the $d_{32}$ and $h_{112}$ proton orbitals around Z=73. Proton separation energies are compared with mass model predictions.

Nuclear Structure and Decay Data for A=149 Isobars
2022, Nuclear Data Sheets
Experimental nuclear structure and decay data are evaluated for all the 17 known nuclides of mass 149 (Xe, Cs, Ba, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb). Detailed compiled and evaluated spectroscopic information is presented for each reaction and decay dataset, and recommended values are provided for level properties, α, β and γ radiations, and other spectroscopic parameters, based on an evaluation of all the available experimental data for A=149 isobaric nuclides. Although large amounts of nuclear spectroscopic data are available for nuclides of A=149, yet large gaps in knowledge exist, as described below. For the lowest atomic number nuclide ¹⁴⁹Xe, only the isotopic identification has been made, with no data for its ground-state half-life. For ¹⁴⁹Cs, ¹⁴⁹Tm and ¹⁴⁹Yb information is available for only the respective ground states. For ¹⁴⁹Ba, ¹⁴⁹La and ¹⁴⁹Er, limited data exist for excited states. Many of the decay schemes of radioactive nuclei of A=149 are considered as incomplete, either due to large energy differences between the highest observed excited states in daughter nuclides and the respective Q-values, or due to the lack of confirmed γ-ray data, as listed below: ¹⁴⁹Cs → ¹⁴⁹Ba, ¹⁴⁹Ba → ¹⁴⁹La, ¹⁴⁹La → ¹⁴⁹Ce, ¹⁴⁹Ce → ¹⁴⁹Pr, ¹⁴⁹Pr → ¹⁴⁹Nd, ¹⁴⁹Tb(4.17 min) → ¹⁴⁹Gd, ¹⁴⁹Ho(21.0 s and 56 s) → ¹⁴⁹Dy, ¹⁴⁹Er(4 s and 9.6 s) → ¹⁴⁹Ho, and ¹⁴⁹Tm → ¹⁴⁹Er. No data exist for the decay of ¹⁴⁹Yb to ¹⁴⁹Tm. Data for half-lives of the excited states in this mass chain are generally lacking as given below by the number of excited levels of known half-life / approximate number of known levels in a nuclide: 2/17 for ¹⁴⁹Ba, 0/18 for ¹⁴⁹La, 3/53 for ¹⁴⁹Ce, 3/44 for ¹⁴⁹Pr, 17/110 for ¹⁴⁹Nd, 9/90 for ¹⁴⁹Pm, 10/210 for ¹⁴⁹Sm, 2/125 for ¹⁴⁹Eu, 6/270 for ¹⁴⁹Gd, 5/200 for ¹⁴⁹Tb, 3/80 for ¹⁴⁹Dy, 3/90 for ¹⁴⁹Ho, and 3/14 for ¹⁴⁹Er. This work supersedes earlier evaluations of A=149 nuclides published by 2004Si16, 1994Si18, 1985Sz01 and 1976Ho17.
Proton decay of actinide nuclei
2020, Nuclear Physics A
The half-lives of one-proton emitters in the actinide region are presented using the coulomb and proximity potential method. The studied proton decay half-lives are compared with that of other decay modes such as alpha decay, spontaneous fission and beta decay. We have identified proton emitters in the actinide region and also it is the competing decay mode for all the observed proton emitters. We have included the effects of deformations in the present study. One-proton decay half-lives of present study have shown good agreement with the available experimental values.
Nuclear data sheets for A = 149
2004, Nuclear Data Sheets
Nuclear spectroscopic information for known nuclides of mass number 149 (Cs,Ba,La,Ce,Pr,Nd,Pm,Sm,Eu, Gd,Tb,Dy,Ho,Er,Tm,Yb) with Z=55 to 70 and N=94 to 79 have been evaluated and presented together with adopted energies and Jπof levels in these nuclei. No excited state data are yet available for ¹⁴⁹Cs, ¹⁴⁹Ba, ¹⁴⁹La, ¹⁴⁹Tm and ¹⁴⁹Yb. The existence of ¹⁴⁹Cs is reported from mass separation of products from U(p,X) reaction and that of ¹⁴⁹Yb from proton decays of ¹⁵⁰Lu g.s. and ¹⁵⁰Lu isomer. There are no half-life data for ¹⁴⁹Cs and ¹⁴⁹Yb. In ¹⁴⁹Gd, 12 excited superdeformed bands have been reported, in addition to the yrast (g.s.) superdeformed band. In ¹⁴⁹Tb, five superdeformed bands are known, whereas in ¹⁴⁹Dy there is some evidence of superdeformation, but no discrete gamma rays have been found. The half-life of fully-ionized ¹⁴⁹Dy isomer at 2661 keV has been reported to be 11 s, as compared to 0.49 s for the neutral atom. This evaluation supersedes previous full evaluations of A=149 by Nucl. Data Sheets 46 (1985) 1 and Nucl. Data Sheets 19 (1976) 337 and a midstream (in update mode) evaluation by Nucl. Data Sheets 73 (1994) 351
Half-lives for proton emission, alpha decay, cluster radioactivity, and cold fission processes calculated in a unified theoretical framework
2002, Atomic Data and Nuclear Data Tables
Half-life values of spontaneous nuclear decay processes are presented in the framework of the effective liquid drop model (ELDM) using the combination of varying mass asymmetry shape description for the mass transfer (VMAS) and Werner-Wheeler's inertia coefficient (WW). The calculated half lives of ground-state to ground-state transitions for proton emission, alpha decay, cluster radioactivity, and cold fission processes are compared with experimental data. These comparisons show that the ELDM is a very efficient model to describe these different decay processes in a same, unified, theoretical framework. A table listing the predicted half-life values, τ_c, is presented for all possible cases of spontaneous nuclear breakup such that −7.30≲log₁₀τ_c [s]≲27.50 and log₁₀(τ/τ_c)>−17.0, where τ is the total half life of the parent nucleus.

Heavy ion radiation damage in double-sided silicon strip detectors
1996, Nuclear Instruments and Methods in Physics Research, Section A: Accelerators, Spectrometers, Detectors and Associated Equipment
A ²⁵²Cf fission fragment source was used to produce heavy-ion radiation damage in a double-sided silicon strip detector. It was found that a good quality fission fragment spectrum (as determined by the peak to valley ration $N_{L} N_{V}$ ) could not be achieved for radiation incident on the p⁺ face of the detector. However, for radiation incident on the n⁺ face, the ratio $N_{L} N_{V}$ remained adequate up to an accumulated dose of ∼4×10⁶ fragments mm⁻². For the measurement of alphas, typical resolution deteriorated from an initial 30 keV FWHM to 50 keV FWHM at a dose of ∼8×10⁶ fragments mm⁻² for incident on the n⁺ face, and ∼6×10⁶ for radiation incident on the p⁺ face. The interstrip resistance in one region of the n⁺ face broke down completely after a relatively small radiation doses incident on that face. Further investigation of this is still required.
