Abstract Neutron separation energies in 91Zr, 92Zr, 93Zr and 95Zr were determined by measurements of relative Q-values for (d, p) reactions on Zr isotopes. A comparison is made with separation energies derived from a previous measurement of (d, t) reaction Q-values. The neutron separation energy in 95Zr disagrees by three standard deviations with the adjusted value in the 1977 Atomic Mass Evaluation.

The spectroscopic factor (SF) of doubly-magic nuclei, neutron shell closed and neutron-rich nuclei has been determined through ([Formula: see text], [Formula: see text]) reaction in the projectile energy range from 3 to 26[Formula: see text]MeV. The theoretical angular differential cross-sections of ([Formula: see text], [Formula: see text] reactions in scattering center-of-mass angles from [Formula: see text] to [Formula: see text] have been calculated using FRESCO and NRV-DWUCK5 codes. By comparing the theoretical angular differential cross-sections with available experimental angular differential cross-sections, the values of SF have been determined. The exponential increase of SF as a function of neutron separation energy normalized by spin of the recoil nuclei has been shown for the first time for doubly-magic nuclei. The similar type of trend has also been observed for neutron-rich as well as neutron shell closed nuclei as a function of neutron separation energy normalized by asymmetric factor of recoil nucleus. More experimental data are required to verify the trend predicted by this investigation.

Analysis Of Binding Energy

We study the extremely neutron-rich nuclei for Z = 17–23, 37–40 and 60–64 regions of the periodic table by using axially deformed relativistic mean field formalism with NL3* parametrization. Based on the analysis of binding energy, two neutron separation energy, quadrupole deformation and root mean square radii, we emphasized the speciality of these considered regions which are recently predicted islands of inversion.

Q Values

Relative Q-values for (d, p) and (d, t) reactions on all even-A tin isotopes have been determined by simultaneous detection in nuclear emulsions placed in the focal plane of a magnetic spectrograph of the particle groups corresponding to the ground state transitions. The results when combined to other input data for the atomic mass tables provide more accurate mass excesses for nuclides in this mass region.

Values derived from mass spectral doublets are reported for the following mass differences: Hg200−Hg198, Hg201−Hg199, Hg202−Hg200, Hg204−Hg202, Tl205−Tl203, Pb206−Pb204, Pb208−Pb206, Bi209−Pb207, Pb207−Tl205, Pb206−Hg204, and Tl203−Hg201. These mass differences are combined with existing reaction and disintegration data to yield single- and double-neutron separation energies for several of the isotopes of the above elements. The resulting neutron separation energy curves for even N are strikingly similar in shape and all exhibit an abrupt change in slope at N = 124. The curves for odd N do not display the same regularity. Currently accepted values for the total decay energies Tl204–Hg204 and Tl202–Hg202 are probably too large and too small, respectively, but current values for Pb205–Tl205 and Bi208–Pb208 are confirmed.
