Decay study of neutron-deficient101In

Discovery of the calcium, indium, tin, and platinum isotopes

“…These results are compatible only with the reactions 40 Ca(p, d2n) 37 Ca and 39 K(p, 3n) 37 Ca, whose calculated laboratory energy thresholds are 44.6 and 38.5 MeV. This establishes the activity as following the decay of 37 Ca''. Reeder et al used the 60 in.…”

“…Combining this with the uncertainties associated with (1) beam energy (10 keV), (2) scattering angle (5 keV), (3) focal plane calibration (15 keV), target thickness (20 keV) along with the 8 He mass excess of 31.601 ± 0.013 MeV, we find the reaction Q value to be −57.58 ± 0.04 MeV, and the mass of 36 Ca to be −6.44 ± 0.04 MeV''. 37 Ca…”

“…The discovery of 37 Ca was simultaneously reported in 1964 by Hardy and Verrall in Calcium-37 [7] and Reeder et al in "New Delayed-Proton Emitters: Ti 41 , Ca 37 , and Ar 33 " [8]. Hardy and Verrall bombarded a calcium target with an 85 MeV proton beam from the McGill synchrocyclotron.…”

“…Hardy and Verrall bombarded a calcium target with an 85 MeV proton beam from the McGill synchrocyclotron. The delayed proton spectrum was measured with a surface barrier silicon detector to identify the presence of 37 Ca. "The threshold for production from stable calcium (97% 40 Ca) was found to be 7 MeV higher than that from potassium (93% 39 K), and was approximately 47 MeV.…”

Nuclear structure study of the neutron deficient cadmium isotopes100, 101, 102Cd

“…The level order is based on the following arguments. The 252-and 892-keV 7-rays have been observed to be strong transitions in the/?+/EC decay of the l~ ground state which is most probably Is=(9/2 +) [28]. From the systematics of the heavier odd Cd isotopes the 252 keV transition is assigned as the (7/2)-,(5/2) transition to the a~ ground state (see [29] for most probable spin assignment).…”
