The study [Nucl. Phys. A 722 (2003) 424c] of the neutron rich nuclei near the N=28 magic number was performed at GANIL-France. This letter reports on preliminary results concerning isotopes 44,45,46Ar. Schemes of excited levels were deduced from the γ–γcoincidences. Levels above Sn ...
Cosmic‐ray prdocution rates of helium, neon and argon isotopes in H chondrites based on chlorine‐36/argon‐36 ages The results confirm model calculations which predict that the relationship between 21Ne production rates and 22Ne/21Ne is ambiguous for high shielding. Besides the mean 38Ar pro...

It is possible from the present data to make only a very rough calculation of the number of such tracks compared with the number of recoil protons, but it is estimated that the proportion may be as high as one quarter. These experiments have been made with the active support of Dr. J....
A number of low-energy transitions have been observed when a Ge(Li) detector is irradiated with neutrons having a broad spectrum of energies. Some of the t... RL Bunting,JJ Kraushaar - 《Nuclear Instruments & Methods》 被引量: 60发表: 1974年 Nuclear Spin Symmetry Conservation and Relaxation...
Accordingly, it has the largest NπNν value (Nπ and Nν are the number of proton and neutron pairs outside the closest magic number. This product is considered to be a good indicator of deformation [128]) of any isotope below A=208 and thus it is naively expected to have the ...
