A β-decay experiment on nuclei in the region of N=28 has been performed at the GANIL facility. New measured half-lives for the Si isotopes from N=25 to N=28 are reported and discussed in the light of the deformation occuring in this region. Comparison with QRPA calculations suggests that a weakening of the spin-orbit force occurs for the very neutron-rich Si isotopes.

Nuclear Data Sheets for A=40
2017, Nuclear Data Sheets
The experimental nuclear structure data and decay data are evaluated for the known nuclides of mass 40 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed evaluated nuclear structure information is presented with the best values recommended for level energies, half-lives, γ-ray energies and intensities, decay properties (energies, intensities and placement of radiations), and other spectroscopic data. The ⁴⁰Ca and ⁴⁰K nuclides remain as the most extensively studied from many different reactions and decays; no excited states are known in ⁴⁰Mg, ⁴⁰Al, ⁴⁰P and ⁴⁰Ti. This work supersedes the earlier full evaluation of A=40 by J. Cameron and B. Singh (2004Ca38).
Nuclear Data Sheets for A = 42
2016, Nuclear Data Sheets
The experimental data are evaluated for known nuclides of mass number A = 42 (Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti, V, Cr). Detailed evaluated level properties and related information are presented, including adopted values of level and γ–ray energies, decay data (energies, intensities and placement of radiations), and other spectroscopic data. This work supersedes earlier full evaluations of A = 42 published by B. Singh, J.A. Cameron – Nucl.Data Sheets 92, 1 (2001) and P.M. Endt – Nucl. Phys. A521, 1 (1990); Errata and Addenda Nucl. Phys. A529, 763 (1991); Errata Nucl. Phys. A564, 609 (1993) (also P.M. Endt – Nucl. Phys. A633, 1 (1998) update).
No excited states are known in ⁴²Al, ⁴²P, ⁴²V and ⁴²Cr, and structure information for ⁴²Si and ⁴²S is quite limited. There are no decay schemes available for the decay of ⁴²Al, ⁴²Si, ⁴²P, ⁴²V and ⁴²Cr, while the decay schemes of ⁴²Cl and ⁴²Ti are incomplete in view of scarcity of data, and large gap between their Q–values and the highest energy levels populated in corresponding daughter nuclei. Structures of ⁴²Ca, ⁴²K, ⁴²Sc and ⁴²Ar nuclides remain the most extensively studied via many different nuclear reactions and decays.
Nuclear Data Sheets for A = 41
2016, Nuclear Data Sheets
Available information pertaining to the nuclear structure of all nuclei with mass numbers A=41 ranging from Al (Z=13) to Ti (Z=22) are presented. The experimental reaction and decay data are evaluated and any inconsistencies or discrepancies are noted. The adopted values for various level properties (such as the spin, parity and and halflife) and gamma properties (energy, intensity and multipole character) are given.
Since the prior evaluation several new measurements have expanded our knowledge of A=41 nuclides. The half-life of the ground state of ⁴¹Si has been determined and a single excited state identified. Excited levels in ⁴¹P have been observed for the first time. In ⁴¹Cl, seven new excited states have been identified in deep inelastic and heavy ion transfer reactions. Half-lifes for four states in ⁴¹Ar have been updated and additional levels with gammas have been included from a new measurement using the multiple ion transfer reaction. In ⁴¹Ca via charge-exchange reaction measurements, several new excited states were observed. A number of new resonances in ⁴¹K have been identified via the (p,γ) reaction.
There remains a significant discrepancy in the half-life of the first excited state (980 keV) in ⁴¹K, with measurements differing by more than an order of magnitude. Transfer reactions suggest that this M1 transition should be l-forbidden, however, several measurements yield a lifetime which suggests a sizable M1 strength. Further measurements to resolve the current conflicts would be beneficial.
Nuclear data sheets for A = 39
2006, Nuclear Data Sheets
Nuclear spectroscopic information for the known nuclides of mass 39 (Mg,Al,Si,P,S,Cl,Ar,K,Ca,Sc,Ti) has been evaluated. The principal sources of the ‘adopted levels’ presented are Endt's evaluations (1990En08, 1978En02). The data sets for reactions and decays, including all available gamma–ray data, are based mostly on the original literature. There are no data available for the excited states in ³⁹Mg, ³⁹Al, ³⁹Si and ³⁹Ti.
Nuclear Data Sheets for A=39
2018, Nuclear Data Sheets
Experimental nuclear structure data from various reactions and decays have been evaluated for all known nuclides of mass 39 (Mg, Al, Si, P, S, Cl, Ar, K, Ca, Sc, Ti). Detailed evaluated nuclear structure information is presented for each reaction and decay and the best values combining all available data are recommended for level energies, half-lives, γ-ray energies and intensities, decay properties (energies, intensities and placement of radiations), and other spectroscopic data. The ³⁹K, ³⁹Ca and ³⁹Ar are the most extensively studied nuclides; no excited states are known in ³⁹Mg and ³⁹Ti. This work supersedes the earlier full evaluation of A=39 by B. Singh and J. Cameron (2006Si02).
