AbstractAbstract
[en] It is well known that in nature no isotopes exist with 43 protons (technetium) or 61 protons (promethium) and which are stable with respect to β decay. It has been noted that there also exist no stable isotopes with the number of neutrons equal to 19, 21, 35, 39, 45, 61, 71, 89, 115, or 123. One gets the impression that β-stable nuclei with these numbers of neutrons are forbidden. It has been shown that β-stable isotopes with the same neutron excess N-Z = 2T form a chain of nuclei represented on the neutron-proton diagram by a straight line with slope 45 degrees. All β-stable isotopes can be divided into three families of such straight lines: A-odd, A-even with even values of T, and A-even with odd values of T. The transition from one chain to another (within one family) occurs for definite values of Z which satisfy the condition 2T=(N-Z)∼6x10-3Z2 for Z> 20. In those cases when in the family of A-odd chains the transition occurs for an odd Z, one observes open-quotes forbiddenclose quotes values of the number of neutrons. The authors discuss the application of these models to the observed nuclei with apparently forbidden neutron and proton numbers. 3 refs., 1 fig

AbstractAbstract
[en] A description of the automatic Liquid Scintillation Counting System (LSS-34) designed by Electronics Corporation of India Limited, India is given. The system mainly consists of a detector assembly photo-multiplier tubes, sample changer, fast electronics timer dual counter, control unit and printer. The system provides precision counting of soft β emitting radioisotopes such as C14 and H3. (A.K.)

AbstractAbstract
[en] The combinations of the H-number and a coincidence type counter make possible the determination of the DPM of beta emitters by employing a single extrapolation. The method does have some limitations. It is not possible to start with highly quenched 3H containing samples, i.e., R greater than 3.0. The method is probably accurate to within +-3 percent. Further work will be performed to extend this method to a series of beta emitting nuclides and to further define the accuracy
