Mass-excesses for 43Ar ( -31.98 +- 0.07 MeV), $sup 45$Ar ( -29.727 +- 0.06 MeV), and 46Ar ( -29.732 +- 0.07 MeV) were determined from the 48Ca([alpha], 9, 7Be)43, 45Ar reactions at 77.7 MeV and the 48Ca(6Li, 8B)46Ar reaction at 80.1 MeV. Several excited states of 43Ar and 45Ar were observed. These and the excited states of 25Ne are compared with theoretical predictions. Ground state differential cross sections are given for all reactions, ranging from 0.1 to 1 [mu]b/sr at forward angles. Upper limits of about 1 to 25 nb/sr were determined for the ground state cross sections of the reactions $sup 48$Ca([alpha], 8, 1°, 11B)44, 42, 41Cl and $sup 48$Ca([alpha], 1°−sup 13$C)42−sup 39$S at 110 MeV. Recoil coincidence techniques were used to measure the mass-excess of the particle- unbound nucleus 1°Li(33.83 +- 0.25 MeV) by the 9Be(9Be, $sup 8$B)1°Li reaction at 121 MeV; the ground state cross section was 30 nb/sr. The 14C(9Be, 8B)15B reaction at 120 MeV was also investigated using coincidence techniques. Contamination problems only permitted determining a ground state cross section upper limit of 50 nb/sr. A simple mass relation is derived, similar in approach to the Garvey-Kelson method but taking more explicit account of shell effects. Comparison is made with the Garvey- Kelson relation, and predictions of masses and of the stability of neutron-excess light nuclei are given for both methods. The modified mass relation is shown to offer better account for highly neutron-excess nuclei, including the values reported here for 25Ne and 43, 45, 46Ar.

This book was released on 1984 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Historically, masses have been determined one at a time via decay or reaction Q-value measurements. In general only after several such individual measurements could one establish a trend in the binding energies and thus develop an improved understanding of the nuclear mass surface. With the advancement of online mass spectrometers, it became possible to measure long isotopic sequences. Although only alkali elements have been extensively measured to date, this technique has proved successful in revealing sudden changes in nuclear structure and in pointing out systematic deficiencies of various mass models. In the experiment described herein, we have worked to extend mass measurement capabilities one step further with the development of a more general approach in which a whole series of nuclei can be measured simultaneously, independent of their N or Z. Below we demonstrate that direct mass measurements can be performed for fast recoiling nuclei using a combined energy and time-of-flight (i.e., M proportional to ET2) technique.
