High-spin states of 95,97Mo (Z=42, N=53,55) nuclei have been investigated through 82Se(18O, xn) reaction at Eb=60 MeV. The level scheme in 95Mo has been observed upto ≏ 10 MeV in the present experiment. The level structure shows mainly single particle character.
In 97Mo, the ground state level sequence has been extended to ≏ 4.5 MeV while the previous information had been up to 2.4 MeV.
A negative parity band built on 1437 keV (11/2−) excited state has been extended to 5.5 MeV. The structure seems to show a coexistence of single particle and collective
modes of excitation. Properties of both the nuclei have been compared with shell model calculations using OXBASH. 相似文献

The nucleus 30 65 Zn was studied using the 52Cr(16O, 2pn)65Zn reaction at a beam energy of 65 MeV. The level scheme is extended up to an excitation energy of 10.57 MeV for spin-parity (41/2?) with several newly observed transitions placed in it. 相似文献

The use of diffusely scattering materials as a means of eliminating interference fringes has been investigated. Their use
introduces laser speckle that can contribute a random, rather than periodic, uncertainty to gas measurements. We have established
a method for quantifying the uncertainty due to speckle and investigated ways of reducing it. We characterised the speckle
at 823 nm allowing the use of low-cost CCD cameras. We have tested the principle of the model by making gas absorption measurements
on the 1650-nm methane absorption line using wavelength-modulation spectroscopy, for which preliminary results are presented.
